The selections contained in these volumes from the papers and letters of Leibniz are intended to serve the student in two ways: first, by providing a more adequate and balanced conception of the full range and penetration of Leibniz's creative intellectual powers; second, by inviting a fresher approach to his intellectual growth and a clearer perception of the internal strains in his thinking, through a chronological arrangement. Much confusion has arisen in the past through a neglect of the develop ment (...) of Leibniz's ideas, and Couturat's impressive plea, in his edition of the Opuscu/es et fragments (p. xii), for such an arrangement is valid even for incomplete editions. The beginning student will do well, however, to read the maturer writings of Parts II, III, and IV first, leaving Part I, from a period too largely neglected by Leibniz criticism, for a later study of the still obscure sources and motives of his thought. The Introduction aims primarily to provide cultural orientation and an exposition of the structure and the underlying assumptions of the philosophical system rather than a critical evaluation. I hope that together with the notes and the Index, it will provide those aids to the understanding which the originality of Leibniz's scientific, ethical, and metaphysical efforts deserve. (shrink)

In The Souls of Black Folk, W.E.B. Du Bois introduces double consciousness as a result of racial prejudice and oppression. Explained as a state of confliction felt by black Americans, Du Bois presents double consciousness as integral to understanding the black experience. Later philosophers question the importance of double consciousness to current race discussions, but this paper contends that double consciousness provides valuable insights into black and white relations. To do this, I will utilize the modern slang term, “Oreo,” to (...) highlight how a perceived incompatibility between blacks and whites could prevent America from achieving a greater unity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Leibniz on Purely Extrinsic DenominationsGary L. CesarzDennis Plaisted. Leibniz on Purely Extrinsic Denominations. Rochester: University of Rochester Press, 2002. Pp. viii + 128 Cloth, $70.00.Interpreting Leibniz is like trying to flatten a balloon without deflating it; press it here and it bulges there. Press one of his controversial principles and problems result for another. Leibniz on contingent and necessary truths exemplifies this difficulty. So does Leibniz's denial that (...) there are "extrinsic denominations which have no foundationin the denominated thing" (NPE).Plaisted questions the meaning and challenges the current interpretations of this principle. Does "foundation" mean "included in a thing," or "reducible to an intrinsic denomination"? Furthermore, what is the thing denominated? Is it the individual concept of a substance, or an intrinsic denomination in the concept of the substance? Leibniz holds, "for all truths the predicate is contained in the subject" (PS) which, in some sense, includes both denominations (Leroy E. Loemker, ed., Gottfried Wilhelm Liebniz: Philosophical Papers and Letters [Dordrecht: Reidel, 1976], 268). This suggests that both denominations have the same status as predicates. However, such statements as, "there is no denomination so extrinsic that it does not have an intrinsic denomination as its basis" (Loemker, 527) and "all extrinsic denominations are founded in intrinsic denominations" (Benson Mates, The Philosophy of Leibniz: Metaphysics and Language [New York: Oxford University Press, 1989], 225) suggest that the former reduce to the latter. The last two quotes seem to trump all hands. But textual citations are seldom enough to settle disputes of this sort.This has inspired two approaches to the question, one reductionistic, the other non-reductionistic. Plaisted adopts a non-reductionistic approach but regards those prior to his as implausible and unsatisfactory (1, 113 n.34). As for reductionism, he claims to "stand [End Page 494] [it] on its head" (1) and denies its "textual merit" (14). Given Plaisted's broad grasp of Leibniz's writings, this is not an oversight of the passages quoted above. Rather, his case depends on reinterpreting the same passages in light of his version of NPE.A reduction, according to some, requires that a relational proposition be logically equivalent (or at least truth-functionallyequivalent) to a set of non-relational propositions. For others, implication is sufficient, i.e., for a given relational proposition z, and two non-relational propositions x and y, it is impossible that (x & y) is true but z false (Mates, 218). In response, Plaisted examines NPE from four angles, including Leibniz's predicate-in-subject notion of truth, the identity of indiscernibles, and two others. However, since all that follows rides on his understanding of PS, let us focus on it.Plaisted's interprets NPE to mean "There are no extrinsic denominations of an individual... that are not included in that individual's concept" (11). To support this, he observes that Leibniz applies PS to all truths and often derives NPE from PS. But to justify substituting "included in" for Leibniz's use of "foundation in," Plaisted elects to interpret PS in a troubling way. Now, Leibniz insists that necessary truths state an identity between a subject and predicate, either explicit or implicit, and that the latter are reducible to the former by an a priori proof of finite length. Leibniz further says that identity, as explained above, is the reason that PS holds for necessary truths. Thus, Plaisted infers that "identity" and "having a reason" are equivalent, that this sense of PS generalizes to all truths (24-25), and claims support for his version of NPE. This is a positive result for Plaisted, for from it he infers that extrinsic denominations are included in the individual's concept as directly as intrinsic denominations, hence the latter cannot serve as the foundation for the former (25ff.). But this is problematic.First, it leads him to affirm that some denominations are both extrinsic and intrinsic (75). This is a strange conclusion to consider positive, for it implies that there are two types of intrinsic plus extrinsic denominations. Surely this strains the boundaries of "textual merit" at least as much as Plaisted charges against reductionists. More importantly, even if the equivalence Plaisted presses holds for necessary...

Prominent thinkers such as Jurgen Habermas and Michael Sandel are warning that biomedical enhancements will undermine fundamental political values. Yet whether biomedical enhancements will undermine such values depends on how biomedical enhancements will function, how they will be administered and to whom. Since only few enhancements are obtainable, it is difficult to tell whether these predictions are sound. Nevertheless, such warnings are extremely valuable. As a society we must, at the very least, be aware of developments that could have harmful (...) consequences. Indeed, if important values were to be jeopardized, we should take appropriate measures to protect them. This paper focuses on four central values: solidarity, personal responsibility, equality and autonomy. It delineates the conditions under which biomedical enhancements would undermine these values. It also details the circumstances under which these values would be unaffected by enhancements as well as those under which they would be promoted. Specifying these conditions is valuable; it would enable society to prepare appropriate ethical guidelines and policy responses in advance. (shrink)

Abstract. We argue that all human beings have a special type of dignity which is the basis for (1) the obligation all of us have not to kill them, (2) the obligation to take their well-being into account when we act, and (3) even the obligation to treat them as we would have them treat us, and indeed, that all human beings are equal in fundamental dignity. We give reasons to oppose the position that only some human beings, because of (...) their possession of certain characteristics in addition to their humanity (for example, an immediately exercisable capacity for self-consciousness, or for rational deliberation), have full moral worth. What distinguishes human beings from other animals, what makes human beings persons rather than things, is their rational nature, and human beings are rational creatures by virtue of possessing natural capacities for conceptual thought, deliberation, and free choice, that is, the natural capacity to shape their own lives.

The projection postulate, which prescribes “collapse of the state vector” upon measurement, is not an essential part of quantum mechanics. Rather it is only an optional discarding of certain branches of the state vector that are expected to be irrelevant for the purpose at hand. However, its use is hazardous, and there are examples of repeated measurements for which the conventional application of the projection postulate leads to incorrect results.

The attempt to derive (rather than assume) the statistical postulate of quantum theory from the many-universes interpretation of Everett and De Witt is analyzed The many-universes interpretation is found to be neither necessary nor sufficient for the task.
