In the preface to the second edition of his Critique of Pure Reason, Kant laments thatit still remains a scandal to philosophy and to human reason in general that the existence of things outside us … must be accepted on faith, and if anyone thinks good to doubt their existence, we are unable to counter his doubts by any satisfactory proof. The two editions of the Critique each contain a celebrated refutation of epistemological scepticisms like those of Descartes and Hume. The first edition refutation has been widely decried as relying on an objectionable sort of idealism. The refutation of the second edition, though rather more difficult to interpret than the first, has usually been read as a mere reworking of the first

The last century has seen enormous progress in our understanding of time. This volume features original essays by the foremost philosophers of time discussing the goals and methodology of the philosophy of time, and examining the best way to move forward with regard to the field's core issues. The collection is unique in combining cutting edge work on time with a focus on the big picture of time studies as a discipline. The major questions asked include: What are the implications of relativity and quantum physics on our understanding of time? Is the passage of time real, or just a subjective phenomenon? Are the past and future real, or is the present all that exists? If the future is real and unchanging, how is free will possible? Since only the present moment is perceived, how does the experience as we know it come about? How does experience take on its character of a continuous flow of moments or events? What explains the apparent one-way direction of time? Is time travel a logical/metaphysical possibility?

  ‘Performative’ transcendental arguments exploit the status of a subcategory of self-falsifying propositions in showing that some form of skepticism is unsustainable. The aim of this paper is to examine the relationship between performatively inconsistent propositions and transcendental arguments, and then to compare performative transcendental arguments to modest transcendental arguments that seek only to establish the indispensability of some belief or conceptual framework. Reconceptualizing transcendental arguments as performative helps focus the intended dilemma for the skeptic: performative transcendental arguments directly confront the skeptic with the choice of abandoning either skepticism or some other deep theoretical commitment. Many philosophers, from Aristotle and St. Thomas Aquinas to Jaakko Hintikka, C.I. Lewis, and Bernard Lonergan, have claimed that some skeptical propositions regarding knowledge, reason, and/or morality can be shown to be self-defeating; that is to say, they have claimed that the very upholding of some skeptical position is in some way incompatible with the position being upheld, or with the implied, broader dialectical position of the skeptic in question. Statements or propositions alleged to have this characteristic also sometimes are called ‘self-falsifying,’ ‘self-refuting,’ ‘self-stultifying,’ ‘self-destructive,’ or ‘pointless.’ However, proponents of the strategy of showing skepticism to be self-defeating have not in general adequately distinguished between two types of self-defeating proposition: self-falsifying and self-stultifying. In the first part of this paper I distinguish between self-falsifying and self-stultifying propositions, and introduce the notion of performative self-falsification. In the second part I discuss classical transcendental arguments, ‘modest’ transcendental arguments, and objections to each. In the third part I introduce two types of transcendental argument—each labeled “performative”—corresponding to two types of performatively self-falsifying proposition, and I compare them to modest transcendental arguments

The issue of time-awareness presents a critical challenge for empiricism: if temporal properties are not directly perceived, how do we become aware of them? A unique empiricist account of time-awareness suggested by Hume's comments on time in the Treatise avoids the problems characteristic of other empiricist accounts. Hume's theory, however, has some counter-intuitive consequences. The failure of empiricists to come up with a defensible theory of time-awareness lends prima facie support to a non-empiricist theory of ideas
