In this era of increased polarization of opinion and contentious disagreement, CRITICAL REASONING presents a cooperative approach to critical thinking and formation of beliefs. CRITICAL REASONING emphasizes the importance of developing and applying analytical skills in real life contexts. This book is unique in providing multiple, diverse examples of everyday arguments, both textual and visual, including hard to find long argument passages from real-life sources. The book provides clear, step-by-step procedures to help you decide for yourself what to believe--to be (...) a consumer of information in our contemporary "world of experts.". (shrink)

In the Foundations of the Metaphysics of Morals Kant presented a method for discovering what morality requires us to do in any situation and claimed that it is a method everyone can use. The method consists in testing one's maxim against the requirement stated in the formulations of the categorical imperative. There has been endless discussion of the adequacy of Kant's method in giving moral guidance, but there has been little effort to situate Kant's view of ethical method in its (...) historical context. In this paper I try to do so. I take the label "method of ethics" from the work of Henry Sidgwick. A method of ethics, he says, is any rational procedure by which we determine what it is right for an individual to do or what an individual ought to do. Since the moralists I want to consider do not all think of morality as rational, I shall broaden the notion by saying that a method is any systematic or regular procedure, rational or not, by which we determine what morality requires...

In this paper I wish to propose and defend a form of the Representative Theory of Perception. According to this version of the theory, when a subject perceives some object x to be in a state P1 he does so by being aware of some modfication M1 of some object E. The subject's way of perceiving any one of a range of objects x,y,z, … is that of being aware of some modification of E. It will be a necessary condition (...) of someone's perceiving x to have property P1 that E be modified in some way. And in order for the modifications of E to be representations, a given property P1 will need to be causally related, characteristically, to one or more specific modifications, M1,M2, … Mn, of E. symbolized by ‘X'.).

‘Now that all parts and members of the mortal creature had been fashioned into one, seeing that it must be the creature's lot for reasons of necessity to spend its life in the domain of fire and air and that it was like to waste away being continually melted and emptied by their onslaught, the gods contrived reinforcement for it. Blending a being kindred to man's being but with different shapes and senses, they brought it into life, a second kind (...) of living creature. Trees, plants, and seeds are these, and those among them which are cultivated types to-day have arrived at their mild benevolence to man only because they have been civilized by his husbandry; formerly only the wild kinds existed, for these are older than the cultivated. Now everything that is alive, whatever it be, may perfectly correctly and of right be termed ‘a living creature’. The creature now in question has at any rate the third kind of soul which our discourse told us is situated between the midriff and the navel. This kind of soul has nothing of opining or of reasoning mind, but it has sensation of pleasant and painful with attendant desires. For continually it is subject to every impression. Its manner of birth has not granted it the power to revolve by itself in itself upon itself rejecting outside motion and asserting its own and thus by beholding all things by native endowment of soull to reason out aught of its own concerns. So it has life and is not some second being other than a living creature, but it stays fixed, rooted, motionless, for it has never been granted movement of its own initiation.’. (shrink)

Although the existence of tachyons is not ruled out by special relativity, it appears that causal paradoxes will arise if there are tachyons. The usual solutions to these paradoxes employ some form of the reinterpretation principle. In this paper it is argued first that the principle is incoherent, second that even if it is not, some causal paradoxes remain, and third, the most plausible “solution,” which appeals to boundary conditions of the universe, will conflict with special relativity.

Now it is tempting to try to generalize the view that means-ends considerations play a part in determining what is the right theory. It is tempting, that is, to try to use a similar view to give an account of the nature of truth or knowledge quite generally. For can we not say that truth is simply what we ought to believe, and that knowledge is what we are justified in believing? After all, terms like "true," "false," "probable," "doubtful," "known," (...) "believed," and so on, are not merely descriptive terms. They are used to evaluate the degree to which a belief or proposition is one which we ought to accept. And if in the case of so important an area of human knowledge as scientific theory what we ought to accept is determined in large part by means-ends considerations, may it not be true that in other areas of human knowledge means-ends considerations have a similar function? Perhaps it would even be possible to define truth, or knowledge, in terms of what serves some end or purpose. (shrink)
