In this chapter I assume that we accept, perhaps reluctantly, general facts, that is states of affairs corresponding to universal generalizations. I then argue that, without any addition, this ontology provides us with physical necessities, and moreover with various grades of physical necessity, including the strongest grade, which I call absolute physical necessity. In addition there are consequences for our understanding of time. For this account, which I call the Mortmain Theory, provides a defence of No Futurism (...) against an otherwise serious objection due to David Armstrong. In addition the Mortmain theory enables me to argue against the ‘‘Parmenidean’’ or Block Universe position that future and past are both real. (shrink)

I will discuss the so-called “Master Argument” attributed to Diodorus Cronos in the light of some contemporary speculations on indexicals. In one version, this argument goes as follows: Premise 1. The past, relative to any time t, is necessary. Premise 2. The impossible cannot follow from the possible. Therefore.

This study considers Newton's views on space and time with respect to some important ontologies of substance in his period. Specifically, it deals in a philosophico-historical manner with his conception of substance, attribute, existence, to actuality and necessity. I show how Newton links these “features” of things to his conception of God's existence with respect of infinite space and time. Moreover, I argue that his ontology of space and time cannot be understood without fully appreciating how (...) it relates to the nature of Divine existence. In order to establish this, the ontology embodied in Newton's theory of predication is analysed, and shown to be different from the presuppositions of the ontological argument. From the historical point of view Gassendi's influence is stressed, via the mediation of Walter Charleton. Furthermore, Newton's thought on these matters is contrasted with Descartes's and Spinoza's. In point of fact, in his earliest notebook Newton recorded observations on Descartes's version of the ontological argument. Soon, however, he was to oppose the Cartesian conception of the actuality of Divine existence by means of arguments similar to those of Gassendi. Lastly, I suggest that the nature and extent of Henry More's influence on Newton's conception of how God relates to absolute space and time bears further examination. (shrink)

What is it for something to be essential to an item? For some time, it was standard to think that the concept of necessity alone can provide an answer: for something to be essential to an item is for it to be strictly implied by the existence of that item. We now tend to think that this view fails because its analysans is insufficient for its analysandum. In response, some argue that we can supplement the analysis in terms (...) of necessity with a further condition. In this paper I argue that this view is untenable in its current form. I then provide a glimmer of hope to those who think that essence is at least partially analyzable in terms of necessity. (shrink)

The problem of necessity remains one of the central issues in modern philosophy. The authors of this volume, originally published in 1985, developed a new approach to the problem, which focusses on the logical grammar of necessary propositions. This volume gathers their seminal essays on the problem of necessity, together with new material at the original time publication.

Temporal necessity and the subjunctive conditional appear to be related by the principle of Past Predominance, according to which past similarities and differences take priority over future similarities and differences in determining the comparative similarity of alternative possible histories with respect to the present moment. R. H. Thomason and Anil Gupta have formalized Past Predominance in a semantics that combines selection functions with branching time; in this paper I show that Past Predominance can be formalized and axiomatized using (...) ordinary possible worlds semantics (without branching time).

Kalhat has forcefully criticised Wittgenstein's linguistic or conventionalist account of logical necessity, drawing partly on Waismann and Quine. I defend conventionalism against the charge that it cannot do justice to the truth of necessary propositions, renders them unacceptably arbitrary or reduces them to metalingustic statements. At the same time, I try to reconcile Wittgenstein's claim that necessary propositions are constitutive of meaning with the logical positivists’ claim that they are true by virtue of meaning. Explaining necessary propositions by (...) reference to linguistic conventions does not reduce modal to non‐modal notions, but it avoids metaphysical accounts, which are incapable of explaining how we can have a priori knowledge of necessity.

Normative concepts have a special taste, which many consider to be proof that they cannot be reductively analyzed into entirely nonnormative components. This paper demonstrates that at least some intuitively normative concepts can be reductively analyzed. I focus on so-called ‘hypothetical imperatives’ or ‘anankastic conditionals’, and show that the availability of normative readings of conditionals is determined by features of grammar, specifically features of tense. Properly interpreted, these grammatical features suggest that these deontic modals are analyzable in terms of conditional (...) necessity with a certain temporal structure. (shrink)

_ Source: _Volume 38, Issue 1, pp 129 - 147 The essay investigates elements of sixteenth-century scholastic thought that have played a role in Grotius’s doctrine of necessity: the nature of the rights of the person in extreme need; the relation of the right of necessity to self-preservation; the compact that lies at the origin of property rights; and finally the obligation of restitution once the emergency is over. Grotius did not develop the doctrine of necessity as (...) an abstract principle about the relationship between private property and subsistence rights. Instead, he used it primarily as a normative principle on permissible behavior in times of war. The comparison with sixteenth-century thought and the practical purposes for which he developed the principle help to understand better the Grotian conception about the subjective nature of the right of necessity and its normative foundation.

Metaphysics, as I understand it, is the attempt to construct theories which give correct accounts in general terms of pervasive structural features of reality. Though not precise and not intended as an explicit definition, this characterization is comprehensive enough to include both descriptive and revisionary varieties of metaphysical theory. The enterprise of descriptive metaphysics, Strawson tells us, consists in describing “the actual structure of our thought about the world.” Presumably a philosopher would favor this approach to metaphysics if he or (...) she believed either that the actual structure of our thought about the world provides, at least for the most part, an accurate portrait of the world’s structure or that the actual structure of our thought at any time provides privileged access, or perhaps our only access, at that time to the structure of the world. Revisionary metaphysics, by contrast, is concerned to produce a structure of thought about the world better than the one we actually have. Obviously a philosopher would adopt this approach if he or she believed that the actual structure of our thought about the world provides, in at least some important respects, an inaccurate portrait of the world’s structure and stands in need of revision in the interests of correctness. And clearly a philosopher might hold that the actual structure of our thought is quite accurate in some respects and need only be described to yield correct theory and yet is thoroughly inaccurate in others and requires substantial revision if correct theory is to be the outcome. Philosophers may, as I suppose most of them do, practice by turns descriptive and revisionary kinds of metaphysics. No global commitment to one approach or the other is required; the choice between approaches can be allowed to rest on the exigencies of local problems. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Volitional Necessity and Volitional Shift:A Key to Sobriety?John Talmadge (bio)As a long-time amateur student of philosophy, I think my most effective contribution to this discussion of Dr. Rego's paper will be to discuss Harry Frankfurt's ideas from precisely the point of view of the beginner and the novice. After all, I had never experienced the pleasure of reading Frankfurt until reading Rego, so I can hardly be (...) considered proficient and conversant in analytical philosophy. To pretend to be so would be, in Frankfurt's way of thinking, to construe what I really am (a novice) as what I would ideally like to be (an expert). He calls this "the equation of the real with the ideal," and he certainly gets us thinking. He also says that our failure to mark the distinctions among our many passions (and our attitudes toward our passions) gets us into considerable confusion and trouble.Because I am most familiar with the diagnosis and treatment of addictions, I confine my comments to that domain. I have enjoyed over the years over the puzzling question of whether addiction should actually be called a "disease." This puzzle confounds us for one reason apparent to any armchair philosopher: how can we name something a disease when the removal of the offending agent banishes the problem? I have come to believe that Locke had it right when he said, "We would have a great many fewer disputes in the world if words were taken for what they are, the signs of our ideas only, and not for things themselves." (1994, 122) Addiction is not so much a disease as it is an idea. And this is where I think that Dr. Rego's insights have their most value.In his essay "The Importance of What We Care About," Frankfurt offers a particularly helpful example for those of us interested in the addictions. He observes that there are occasions when we care about something powerfully, and we care about it in such a fashion that we cannot avoid the consequences of the caring. His example from history is Martin Luther, who nailed his declaration to the door of the church with the statement, "Here I stand; I can do no other."It is clear, of course, that the impossibility to which Luther referred was a matter neither of logical nor of causal necessity. After all, he knew well enough that he was in one sense quite able to do the very thing he said he could not do; that is, he had the capacity to do it. What he was unable to muster was not the power to forbear, but the will.(Frankfurt 1988, 86)When an alcoholic finds success through Alcoholics Anonymous, he experiences what I would term a "volitional shift." No longer in the grip of alcohol itself, the alcoholic is constrained by what Frankfurt terms "volitional necessity." The alcoholic has a new constraint to which he declares he is subject, that is, "Today I will remain sober." [End Page 327]Frankfurt says that this capacity—the ability to reflect on ourselves—is precisely what separates us as uniquely human. As Frankfurt sees the world, the will of an agent is identical with the desire that motivates him (or would motivate him if he should act).1A first-order desire, such as the alcoholic's craving for a drink, may be contradicted by a second-order desire, specifically a desire not to crave a drink. The second-order desire is born of the individual's knowledge that the use of alcohol, in his case, will lead to dire consequences in terms of health, happiness, and stability. Frankfurt believes that an addict, for example, typically experiences a desire for the destructive chemical but also a desire not to use the chemical. This second-order desire is the one with which the addict identifies, and this reflects the addict's true self (Frankfurt 1988, 14).If we take Dr. Rego's point and notice how a therapist might approach a patient and define a problem, we see obvious distinctions between different schools of thought. To take three simple examples, consider the following: (a) a... (shrink)

This essay focuses on Spinoza’s claim that ideas of reason are necessary. While Spinoza understands necessity to imply that something cannot be otherwise, the author shows that Spinoza employs a narrower notion of necessity that applies only to some things, what LeBuffe describes as omnipresence: existing at all times and in all places. This account of the sense in which the ideas of reason are necessary makes evident that such ideas have especially strong motivational power. Our affects are (...) more powerful when they represent a thing present, which entails that our ideas representing things as always present and, thus, our ideas of reason are more powerful. On this basis, the author concludes that ideas of reason have a special motivating force, which explains how they serve as commands or dictates. (shrink)

This book offers a major reassessment of Peter Abelard's modal logic and theory of modalities, presenting them as far more uniform and consistent than was until now recognized. Irene Binini offers new ways of connecting Abelard's modal views with other parts of his logic, semantics, metaphysics and theology. Further, the work also provides a comprehensive study of the logical context in which Abelard's theories originated and developed, by presenting fresh evidence about many 11th- and 12th-century sources that are still unpublished. (...) This analysis sheds new light on the relations between Abelard and ancient authors such as Aristotle, Boethius, and Priscian, as well as between Abelard and his contemporaries, such as Anselm of Canterbury, William of Champeaux, Joscelin of Soissons, and Alberic of Paris.

For us, narrative care is grounded in pragmatist philosophy and focused on experience. Narrative care is not merely about acknowledging or listening to people's experiences, but draws attention to practical consequences. We conceptualize care itself as an intrinsically narrative endeavour. In this article, we build on Lugones' understanding of playfulness, particularly to her call to remain attentive to a sense of uncertainty, and an openness to surprise. Playfulness cultivates a generative sense of curiosity that relies on a close attentiveness not (...) only to the other, but to who we each are within relational spaces. Generative curiosity is only possible if we remain playful as we engage and think with experiences and if we remain responsive to the other. Through playfulness, we resist dominant narratives and hold open relational spaces that create opportunities of retelling and reliving our experiences. Drawing on our work alongside older adults, as well as people who work in long‐term care, we show the possibilities of playfulness in the co‐composition of stories across time. By intentionally integrating playfulness, narrative care can be seen as an intervention, as well as a human activity, across diverse social contexts, places and times. (shrink)

What is the temporal structure of conscious experience? While it is popular to think that our most basic conscious experiences are temporally extended, we will be arguing against this view, on the grounds that it makes our conscious experiences depend on the future in an implausible way. We then defend an alternative view of the temporal structure of experience from a variety of different objections. Along the way, we hope to illustrate the wider philosophical ramifications of the relationship between experience (...) and time. What one thinks about the temporal structure of experience is, we believe, deeply interconnected with issues concerning whether consciousness is vague or precise, whether conscious states can be reduced to physical states, whether phenomenal properties are intrinsic properties, and whether phenomenal consciousness can “overflow” access consciousness. As we will see, even seemingly unrelated metaphysical questions, such as the debate between Humean and Non-Humean accounts of natural necessity, bear on questions about the relationship between experience and time.

John Duns Scotus distinguished the ‘convertible’ transcendentals, from ‘disjunctive’ transcendental pairs The latter are mutually exclusive pairs that together cover all of being. This paper investigates the distinctive modal metaphysical account based on the necessary-contingent pair of disjunctive transcendentals, developed by Scotus in approaching the problem of divine foreknowledge and future contingents. Although Scotus commented several times on this problem, only in his Reportatio did he explicitly add a succinct exposition distinguishing between two kinds of contingency and two kinds of (...) necessity. This double understanding of the necessary-contingent pair is first of all systematically and schematically presented in the paper. Subsequently, instead of continuing with the problem of divine foreknowledge as such, the implications of this Scotist framework for an adequate metaphysical understanding of the human will and its freedom will be drawn out. Finally, these schemes are compared to recent literature on the central role of contingency in Scotus’s thought, especially to the research of A. Vos on synchronic contingency and J. Söder on operative contingency. (shrink)

There is a tension between the “growing block” account of time (closed past, open future) and the possibility of backwards time travel. If Tim the time traveler can someday travel backwards through time, then he has (in a certain sense) already been. He might discover this fact before (in another sense) he goes. Hence a dilemma: it seems that either Tim’s future is determined in an odd way or cases of (temporary) ontic indeterminate identity are possible. (...) Either Tim cannot avoid heading for the past or he is only indeterminately that guy who appeared in the past with many of Tim’s memories. Determinacy in the past implies a degree of determinism in the future; indeterminism about the future seeps back to the past. (shrink)

Several authors have detected profound analogies between Kant and Wittgenstein. Their claims have been contradicted by scholars, such being the agreed penalty for attributions to authorities. Many of the alleged similarities have either been left unsubstantiated at a detailed exegetical level, or have been confined to highly general points. At the same time, the 'scholarly' backlash has tended to ignore the importance of some of these general points, or has focused on very specific issues or purely terminological matters. To (...) advance the debate, I distinguish four different topics: questions of actual influence; parallels at the methodological level; substantial similarities in philosophical logic; substantial similarities in the philosophy of mind. The article concentrates on the second and third topic. Section I argues that the critical conception of philosophy shared by Kant and Wittgenstein is itself due to the fact that they explain the a priori status of necessary propositions by reference to the way we experience or represent reality. Section II shows how the Tractatiis linguistically transforms this 'reflective turn', replacing Kant's preconditions of experience by preconditions of symbolic representation. Section III suggests that this explanation of the a priori involves the idea of an isomorphism between thought and reality, and that both Kant's transcendental idealism and Wittgenstein's early metaphysics of symbolism distort this isomorphism. Wittgenstein later rejected this metaphysics of symbolism, on the grounds that language is autonomous, and section IV detects parallels between that idea and Kant's 'diallelus' argument against the correspondence theory of truth. Finally, I claim that while Wittgenstein is right to insist that all a priori propositions are conceptual, Kant, in calling them synthetic a priori, is right to deny that they simply unpack the concepts involved in the propositions themselves.

Recently it has been argued that there are conceivable situations in which we would be led to think of our experiences as belonging to two different, entirely disconnected spaces or times. From this it follows that there is no necessity in the claim that all our experiences must be conceived of as belonging together in one space or time. Let us call the claim that all our experiences must belong to one space and time the connectedness hypothesis, (...) and the counterclaim that there are conceivable situations in which we would be led to think of our experiences as belonging to disconnected spaces or times the discreteness hypothesis. Note that neither of these hypotheses is concerned with the nature of physical space or time: the connectedness hypothesis does not affirm that the universe can be composed only of worlds connected by some path through space or time; it affirms merely that whatever the state of the topology of the universe, we can conceive of our experiences only as related within a single space and time; the discreteness hypothesis does not affirm that the universe may be composed of two or more worlds not connected by some path through space or time; it affirms merely that it is possible for us to find ourselves in a situation where our experiences can be divided into two or more disjoint sets, such that the members of one set cannot be placed in any sort of spatiotemporal relation to the members of any other set. Perhaps either hypothesis could be used as a premise toward a conclusion about the nature of the physical world—but that would be another argument. (shrink)

In the Laws of Thought, Boole establishes a theory of secondary propositions based upon the notion of time. This temporal interpretation of secondary propositions has historically been met with wide disapproval and is usually dismissed in the modern literature as a philosophical non-starter. What was Boole thinking? This paper attempts to give an answer to this question. Specifically, it provides an account according to which Boole’s temporal interpretation follows from his psychologistic conception of logic, in addition to certain background (...) assumptions regarding the psychological necessity of the concept of time. Once Boole’s psychological premises are laid bare, it becomes clearer how he might have viewed the temporal interpretation to be an essential feature of his theory of secondary propositions.

Both Martin Heidegger and Harry Frankfurt have argued that the fundamental feature of human identity is care. Both contend that caring is bound up with the fact that we are finite beings related to our own impending death, and both argue that caring has a distinctive, circular and non-instantaneous, temporal structure. In this paper, I explore the way Heidegger and Frankfurt each understand the relations among care, death, and time, and I argue for the superiority of Heideggerian version of (...) this nest of claims. Frankfurt claims that we should conceive of the most basic commitments which practically orient a person in the world and define his identity (“volitional necessities”) as naturalistic facts, foundational for and located completely without the normative space of reasons. In support of this he appeals to the supposedly foundational role played in human life by the instinct for self-preservation, what Frankfurt calls the “love of living.” The claim is that in questions of practical identity there is a definite priority of the factual over the normative. Frankfurt’s naturalistic model of volitional necessity is motivated by a misunderstanding of the temporal structure of care, a misunderstanding that helps lead him to an implausible conception of the basic structures of human identity. Heidegger advances an anti-naturalistic conception of caring, one bound up with his way of understanding how human beings relate to their own future. I argue that the existential, temporal, and normative significance that Frankfurt attributes to the naturalized “love of living” is better captured by the Heideggerian claim that human identity is defined by being “for-the-sake-of” certain projects and commitments, a way of being lived out in the way Heidegger calls “being-towards-death.”.

Those who interpret quantum mechanics literally are forced to follow some variant of Everett's relative state formulation (or "many worlds" interpretation). It is generally assumed that this is a rather bizarre result that many physicists (especially cosmologists) have been forced into because of the evidence. I look at the history of philosophy, however, reveals that rationalism has always flirted with this very idea, from Parmenides to Leibniz to modern times. I will survey some of the philosophical history, and show how (...) the so-called paradox of quantum superposition can be considered a consequence of basic rationalist assumptions such as the principle of sufficient reason and the identity of indiscernibles.

Baumard's perspective asserts that “opportunity is the mother of innovation,” in contrast to the adage ascribing this role to necessity. Drawing on behavioral ecology and cognition, we propose that both extremes – affluence and scarcity – can drive innovation. We suggest that the types of innovations at these two extremes differ and that both rely on mechanisms operating on different time scales.

The paper offers an explanation of the intuitive appeal of Saul Kripke's necessity of origin thesis, exhibiting it as the consequence of a temporally asymmetrical 'branching model' of possibilities which, in turn, rests on two plausible principles concerning possibility, time, and identity. Unlike some other accounts, my explanation dissociates the necessity of origin thesis from a commitment to individual essences or other sufficient conditions for identity across possible worlds. I conclude that although the branching model is not (...) irresistible, its rejection may necessitate the denial of a plausible principle that requires possibilities for actual individuals to be 'anchored' to their actual characteristics.

Mr A. Quinton has attempted to show that the Kantian doctrine of the necessary unity of space rests ultimately on very general contingencies . More recently, Mr Swinburne has tried to argue the same point for time; and thus he asserts that ‘Kant's unity of time is no more an unalterable necessity of thought than his unity of space’ . I wish to defend Kant against both charges, by showing that the charming stories which Quinton and Swinburne (...) tell, in order to show that there are conceivable circumstances in which space and time would not be unitary, do not succeed in showing this at all.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Possibility and Necessity in the Time of Peter Abelard by Irene BininiWolfgang LenzenIrene Binini. Possibility and Necessity in the Time of Peter Abelard. Investigating Medieval Philosophy Series. Leiden: Brill, 2021. Pp. xii + 326. Hardback, $166.00.This book is an impressive work written by a young Italian scholar who received her PhD only five years ago in Pisa. It is divided into three parts. Part (...) 1 gives a survey of "Early 12th-Century Debates on Modal Propositions"; part 2 is devoted to "Abelard's Modal Logic"; [End Page 327] part 3 deals with the views of "Abelard on the Metaphysics and Epistemology of Modalities." The author displays a profound knowledge of the relevant literature. The primary sources comprise twenty manuscripts preserved in various European libraries, plus forty-eight printed works (from Abelard to William of Sherwood). The list of secondary sources contains altogether 136 items from A (Astroh) to Z (Zagzebski), but, interestingly, it does not mention a monograph that, by its very title, claims to give an exposition of Abelard's logic, namely Maria Teresa Beonio-Brocchieri Fumagalli's La Logica di Abelardo (Firenze: La Nuova Italia, 1964).As far as I can judge (as a nonnative English-speaker), the linguistic quality of Binini's book is quite good. The explanations in the main text, including the translations from Latin sources, are easily comprehensible, and the many quotations (distributed over no less than 655 footnotes) are almost without any fault. Thus, the book rightly deserves inclusion in the prestigious series Investigating Medieval Philosophy. Yet, at least according to my taste, the book contains many redundancies. Again and again, the author first explains a certain issue at some length, then confirms the correctness of her interpretation by means of a longer (English) quotation, and finally reconfirms it by fully quoting the Latin text in the footnotes.As Binini explains in the book's concluding chapter, her aim is to present "an all-encompassing reflection on [Abelard's] works on modalities" and "a comparison between these works and the parallel reflections advanced by other masters and logicians in the early 12th century" (308). She undoubtedly achieves this goal. The comparison of Abelard's views on possibility and necessity with the views of other logicians is mainly carried out in chapters 1–3. Ancient and early medieval logicians such as, in particular, the Stoics and Boethius favored the basic idea that "something," p, is necessary if and only if p is always the case (or true). Accordingly, p is possible if and only if p is at least sometime the case. Abelard, however, was not willing to accept that each possibility has to become realized at some time. He instead offered a "nature-based characterization of possibility" that can "account for unrealized, past, counterfactual, and even unactualizable possibilities" (308). Abelard's idea is that something, x, is possibly a P if and only if the property of being P is compatible with the nature of x. Hence this view basically amounts to a de re conception of possibility that attributes modalities to things, while the temporal view attributes modal properties primarily to propositions (or states of affairs) and hence can be labeled de dicto (or de sensu).Let us now turn to Binini's twofold aim (as formulated on the back cover of her book) to present a "uniform and consistent" reassessment of Abelard's theory of modalities and of his modal logic. The former task is tackled in chapters 8–10. After summarizing, in chapter 8, Abelard's general views on "Nature and Modalities," chapter 9 is devoted to a detailed discussion of the "Many Senses of Possibility." In five consecutive sections, Binini investigates the conception of (1) possibility as "non-repugnancy with nature" (illustrated by the thesis that "any man can be a bishop" [235]); (2) unrealizable but "conceivable" possibilities (such as the existence of humans lacking the ability to laugh [240]); (3) determinate potencies (like that of an amputee who nevertheless "can walk" [248]); (4) past and counterfactual potencies (like that of a blind person who might be able to see); and (5) other puzzling de re possibilities (such as "irrational humans" [261]).The final...

A discussion of Aristotle’s thought on determinism and culpability, Necessity, Cause, and Blame also reveals Richard Sorabji’s own philosophical commitments. He makes the original argument here that Aristotle separates the notions of necessity and cause, rejecting both the idea that all events are necessarily determined as well as the idea that a non-necessitated event must also be non-caused. In support of this argument, Sorabji engages in a wide-ranging discussion of explanation, time, free will, essence, and purpose in (...) nature. He also provides historical perspective, arguing that these problems remain intimately bound up with modern controversies. “ Necessity, Cause and Blame would be counted by all as one of Sorabji’s finest. The book is essential for philosophers—both specialists on the Greeks and modern thinkers about free will—and also compelling for non-specialists.”—Martha Nussbaum “Original and important . . . The book relates Aristotle’s discussions to both the contemporary debates on determinism and causation and the ancient ones. It is especially detailed on Stoic arguments about necessity . . . and on the social and legal background to Aristotle’s thought.”— Choice “It is difficult to convey the extraordinary richness of this book. . . . A Greekless philosopher could read it with pleasure . . . At the same time, its learning and scholarship are enormous.”—G. E. M. Anscombe, Times Literary Supplement. (shrink)
