Thomas S. Kuhn's classic book is now available with a new index.

A scientific community cannot practice its trade without some set of received beliefs. These beliefs form the foundation of the "educational initiation that prepares and licenses the student for professional practice". The nature of the "rigorous and rigid" preparation helps ensure that the received beliefs are firmly fixed in the student's mind. Scientists take great pains to defend the assumption that scientists know what the world is like...To this end, "normal science" will often suppress novelties which undermine its foundations. Research (...) is therefore not about discovering the unknown, but rather "a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education". (shrink)

It is my view that one essential difference between persons and other creatures is to be found in the structure of a person's will. Besides wanting and choosing and being moved to do this or that, men may also want to have certain desires and motives. They are capable of wanting to be different, in their preferences and purposes, from what they are. Many animals appear to have the capacity for what I shall call "first-order desires" or "desires of the (...) first order," which are simply desires to do or not to do one thing or another. No animal other than man, however, appears to have the capacity for reflective self-evaluation that is manifested in the formation of second-order desires. (shrink)

D. In doing x an agent acts incontinently if and only if: 1) the agent does x intentionally; 2) the agent believes there is an alternative action y open to him; and 3) the agent judges that, all things considered, it would be better to do y than to do x.

A fellow of Trinity College, Cambridge, and of the Royal Society, William Clifford (1845–79) made his reputation in applied mathematics, but his interests ranged far more widely, encompassing ethics, evolution, metaphysics and philosophy of mind. This posthumously collected two-volume work, first published in 1879, bears witness to the dexterity and eclecticism of this Victorian thinker, whose commitment to the most abstract principles of mathematics and the most concrete details of human experience resulted in vivid and often unexpected arguments. Volume 2 (...) shows Clifford's thorough engagement with scientific thought as a method for illuminating ethical and moral questions. Essays such as 'Body and Mind', 'On the Scientific Basis of Morals' and 'The Ethics of Belief' all variously demonstrate Clifford's core tenet: that beliefs - whether they guide human action or scientific enquiry - 'can never suffer from investigation'.

An attempt to analyse what it is for belief to be based on reasons becomes involved with questions about the goodness of reasons and the gettier examples. intuitions about knowledge and the "gettier effect" can be used to decide when reasoning has occurred and what reasoning there has been. explanation by reasons is not deterministic.

Even if many instances of reflexive, and even of interpersonal, deception do not involve knowledge or belief of the deceiver to the contrary of the belief he fosters, it is conceivable that some instances could. This is obscured in Stanley Paluch's treatment of self?deception by the dubious contention that one couldn't be self?deceived if one could affirm that one knew (was aware) that P and believed not?P, and that one couldn't be described as knowing P and believing not?P unless one (...) could affirm this (Inquiry, Vol. 10, 1967). The former claim would actually render the affirmation absurd, which it is not; and if it is not, the latter claim is harmless. Whatever can be said of ?self?deception? involving deviant uses of ?know?, the question remains how ?X knows P and believes not?P? could be true given a standard use. The standards of rationality permit one to sustain rival beliefs so long as one does not reflect on all the facts alleged in one of the beliefs. Self?deceit relies on withholding attention not from an unwanted belief as such, as Demos suggests, but from its detailed contents. (shrink)
