Most words are like small vessels with constantly changing contents. Life does not wait for adjustments in language, but seeks to give an immediate solution to its most imperative needs and interests. It builds up and sometimes destroys. It is a panorama in flux.

Strange as it may seem, the traditional principle of causality is based on two contradictory assumptions, both of which are generally accepted, explicitly or implicitly, by the contemporary physicists as well as philosophers. That they are not always willing to acknowledge this paradoxical fact, does not save them from the perplexing situation. The two assumptions, in brief, are: That nothing can act at a distance or across an interval of time, without something mediating between the bodies or events; and That (...) every cause precedes its effect and may be located at a distance from it.

Extensive and profound as philosophic speculation on the nature of knowledge may have been during the last twenty-five centuries, it must be conceded that it has, on the whole, failed in its undertaking. In fact, we do not seem to be much closer to the solution of the epistemological problem than were Kant and Hegel or, for that matter, Plato and Aristotle. Obviously enough, the problem should now be approached in some new way, perhaps one growing out of recent scientific (...) findings. (shrink)

Many centuries ago, at the very beginning of the systematic development of philosophy, Plato declared that the thinker's domain comprises “the wholeness of things;” and indeed, the earlier thinkers took all knowledge for their province and did not hesitate to discuss problems now referred to art, psychology, economics, mathematics, or physics. Since then the meaning of philosophy has appreciably changed, however, and the intellectual descendants of the great founder of the Academy no longer claim the monopoly of all fields of (...) study. For there appeared in the meantime a mighty competitor—or should we say a partner?—in the pursuit of truth, namely, science. (shrink)

Let us take an example that Bernard Williams (1981: 102) made famous. Suppose that you want a gin and tonic, and you believe that the stuff in front of you is gin. In fact, however, the stuff is not gin but petrol. So if you drink the stuff (even mixed with tonic), it will be decidedly unpleasant, to say the least. Should you choose to drink the stuff or not?

Here is a definition of knowledge: for you to know a proposition p is for you to have an outright belief in p that is correct precisely because it manifests the virtue of rationality. This definition resembles Ernest Sosa’s “virtue theory”, except that on this definition, the only virtue that must be manifested in all instances of knowledge is rationality, and no reductive account of rationality is attempted—rationality is assumed to be an irreducibly normative notion. This definition is compatible with (...) “internalism” about rationality, and with a form of “pragmatic encroachment” on the conditions of rational outright belief. An interpretation is given of this definition, and especially of the sense of ’because’ that it involves. On this interpretation, this definition entails that both safety and adherence are necessary conditions on knowledge; it supports a kind of contextualism about terms like ‘knowledge’; and it provides resources to defend safety, adherence, and contextualism, against some recent objections.

Often, when one faces a choice between alternative actions, there are reasons both for and against each alternative. On one way of understanding these words, what one “ought to do all things considered (ATC)” is determined by the totality of these reasons. So, these reasons can somehow be “combined” or “aggregated” to yield an ATC verdict on these alternatives. First, various assumptions about this sort of aggregation of reasons are articulated. Then it is shown that these assumptions allow for the (...) proof of a “Reasons Aggregation Theorem” – parallel to John Harsanyi’s 1955 “Social Aggregation Theorem”. All reasons for action are grounded in reason-providing values; and, for every such reason-providing value, there is in principle a way of measuring how strongly this value counts against each alternative. The theorem tells us that the appropriate measure of how much reason ATC there is against each alternative is simply a weighted sum of the strengths with which these values count against that alternative; the agent ought not ATC to perform an action iff there is ATC more reason against it than against some available alternative.

Intuitively, it seems that some belief-forming practices have the following three properties: 1. They are rational practices, and the beliefs that we form by means of these practices are themselves rational or justified beliefs. 2. Even if in most cases these practices reliably lead to correct beliefs (i.e., beliefs in true propositions), they are not infallible: it is possible for beliefs that are formed by means of these practices to be incorrect (i.e., to be beliefs in false propositions). 3. The (...) rationality of these practices is basic or primitive. That is, the rationality of these practices is not due simply to the availability, by means of some process of reasoning that relies purely on other practices, of a rational or justified belief in the reliability of these practices. -/- How can there be such practices? This paper offers an answer to that question. (shrink)

In this paper, I apply the "conceptual role semantics" approach that I have proposed elsewhere (according to which the meaning of normative terms is given by their role in practical reasoning or deliberation) to the meaning of the term 'ought'. I argue that this approach can do three things: It can give an adequate explanation of the special connection that normative judgments have to practical reasoning and motivation for action. It can give an adequate account of why the central principles (...) of deontic logic are correct. It can give an explanation of the precise ways in which the term 'ought' is systematically context-sensitive, so that the term expresses different (but systematically related) concepts in different contexts.

This essay offers an account of the truth conditions of sentences involving deontic modals like ‘ought’, designed to capture the difference between objective and subjective kinds of ‘ought’ This account resembles the classical semantics for deontic logic: according to this account, these truths conditions involve a function from the world of evaluation to a domain of worlds (equivalent to a so-called “modal base”), and an ordering of the worlds in such domains; this ordering of the worlds itself arises from two (...) further elements – a probability function and a value function – since this ordering ranks the worlds in accordance with the expected value of certain propositions that are true at those worlds. Thus, a proposition of the form ‘Ought (p)’ is true at a world of evaluation w if and only if p is true at all the top-ranked worlds in the domain assigned to w. This domain of worlds consists of metaphysically possible worlds, while the probability function is defined over a space of epistemically possible worlds (which may include metaphysically impossible worlds, such as worlds where Hesperus is not Phosphorus). Evidence is given that this account assigns the correct truth conditions to a wide range of sentences involving ‘ought’. Since these truth conditions involve both a domain of metaphysically possible worlds and a space of epistemically possible worlds, there are two corresponding kinds of conditional involving ‘ought’, depending on which space of worlds is restricted by the conditional. Finally, some objections that might be raised against this account are answered. (shrink)

What reasons for action do we have? What explains why we have these reasons? This paper articulates some of the basic structural features of a theory that would provide answers to these questions. According to this theory, reasons for action are all grounded in intrinsic values, but in a way that makes room for a thoroughly non-consequentialist view of the way in which intrinsic values generate reasons for aaction.

Many philosophers have claimed that the intentional is normative. (This claim is the analogue, within the philosophy of mind, of the claim that is often made within the philosophy of language, that meaning is normative.) But what exactly does this claim mean? And what reason is there for believing it? In this paper, I shall first try to clarify the content of the claim that the intentional is normative. Then I shall examine a number of the arguments that philosophers have (...) advanced for this claim (and for the parallel claim that meaning is normative). As we shall see, many of these arguments are unsuccessful. However, I shall close by giving a sketch of what may be a successful argument for this claim. (shrink)

Richard Price’s moral epistemology provides a distinctive account, not only of the sources of our moral knowledge, but also of its limits – that is, of the moral truths that we do not and even cannot know. According to this moral epistemology, the fundamental moral truths are necessary rather than contingent; if they are knowable at all, they are knowable a priori. In general, fundamental moral truths are akin to mathematical truths. Specifically, these necessary moral truths are grounded in the (...) essences of act-types, which are knowable through ‘intuition’ if knowable at all. However, Price firmly rejects utilitarianism, recognizing several different ‘branches of virtue’, which can conflict with each other. As he argues, we cannot know the truth about act-types that exemplify such conflicting branches of virtue if the competing considerations are too finely balanced. This view of moral epistemology is compared with those of several other philosophers, including W. D. Ross. It is argued that Price has a more unified view than Ross: for Price, all moral knowledge flows from a priori intuition, but this is compatible with our being ignorant of many of the fine details of the fundamental truths of morality.

This chapter is concerned with the distinction that most contemporary epistemologists express by distinguishing between “propositional” and “doxastic” justification. The goal is to develop an account of this distinction that applies, not just to full or outright beliefs, but also to partial credences—and indeed, in principle, to attitudes of all kinds. The standard way of explaining this distinction, in terms of the “basing relation”, is criticized, and an alternative account—the “virtue manifestation” account—is proposed in its place. This account has a (...) certain kinship with the epistemological approach that is known as “reliabilism”, but it also has certain key differences—above all, it is compatible with an internalist view of rationality.

In a century where humans and machines—powered by artificial intelligence or not—increasingly work together, it is of interest to understand human processing of multi-sensory stimuli in relation to attention and working memory. This paper explores whether and when supporting visual information with rhythmic auditory stimuli can optimize multi-sensory information processing. In turn, this can make the interaction between humans or between machines and humans more engaging, rewarding and activating. For this purpose a novel working memory paradigm was developed where participants (...) are presented with a series of five target digits randomly interchanged with five distractor digits. Their goal is to remember the target digits and recall them orally. Depending on the condition support is provided by audio and/or rhythm. It is expected that the sound will lead to a better performance. It is also expected that this effect of sound is different in case of rhythmic and non-rhythmic sound. Last but not least, some variability is expected across participants. To make correct conclusions, the data of the experiment was statistically analyzed in a classic way, but also predictive models were developed in order to predict outcomes based on a range of input variables related to the experiment and the participant. The effect of auditory support could be confirmed, but no difference was observed between rhythmic and non-rhythmic sounds. Overall performance was indeed affected by individual differences, such as visual dominance or perceived task difficulty. Surprisingly a music education did not significantly affect the performance and even tended toward a negative effect. To better understand the underlying processes of attention, also brain activation data, e.g., by means of electroencephalography, should be recorded. This approach can be subject to a future work.

This paper describes differences in two perspectives on the idea of virtue as a theoretical foundation for positive organizational ethics (POE). The virtue ethics perspective is grounded in the philosophical tradition, has classical roots, and focuses attention on virtue as a property of character. The positive social science perspective is a recent movement (e.g., positive psychology and positive organizational scholarship) that has implications for POE. The positive social science movement operationalizes virtue through an empirical lens that emphasizes virtuous behaviors. From (...) a virtue ethics perspective, a behaviorally based account of virtue is a weak theory of virtue. Observations are suggested for integrating the two perspectives. First, virtue should always be understood as an excellence and is often an optimal point between extreme dysfunctions on continuum of potential states. Second, an empirical exploration of virtue needs to account for character and context. Finally, the properties of organization-level virtue need to be further specified and explored. Implications and directions for future research are discussed. (shrink)
