Originally published in 1965 and written by one of the world's leading experts in animal behaviour, this book was written just as the impact of DNA on biology, genetics ethology and biophysics was being felt. The book reviews these developments and analyses the affect they have on our view of our own nature and of ethical and moral sense. It is particularly concerned with the impact of DNA and genetics on philosophic thought.

Published in 1900, this is a collection of one of Britain's most prolific metaphysic thinkers of the 19th century. Fairbrother introduces Thomas Hill Greens moral philosophy on themes such as politics and virtue whilst relating it back to the philosophy of ancient Greece that first inspired Green.

Hume's explicit pronouncements about truth are few and unenlightening. In a well-known passage near the beginning of Book III of the Treatise he writes that ‘Reason is the discovery of truth or falsehood. Truth or falsehood consists in an agreement or disagreement either to the real relations of ideas, or to real existence and matter of fact.’ Hume's main concern in this passage, however, is not with the concept of truth, but with his thesis that moral distinctions are not derived (...) from reason: he introduces his reference to truth only with a view to showing that our ‘passions, volitions and actions … being original facts and realities, complete in themselves,’ are not susceptible of the agreement and disagreement spoken of, and therefore cannot be said to be true or false, in conformity with or contrary to reason. The account of truth given here is not elaborated, and perhaps not even thought to need elaboration. Similarly with another passage a few pages earlier in which Hume says that ‘Truth is of two kinds, consisting either in the discovery of the proportions of ideas, considered as such, or in the conformity of our ideas of objects to their real existence’. Here again his interest is not in truth itself but in ‘curiosity, or the love of truth,’ the passion which, Hume says, ‘was the first source of all our inquiries’. Hume seems to take it for granted that nothing more needs to be said about what it is to discover ‘the proportions of ideas, considered as such,’ or about the circumstances in which we can speak of there being ‘conformity’ or the lack of it between our ideas of objects and their real existence. So far as he is concerned the central point to grasp is the distinction between propositions which have to do with relations of ideas and those which express, or purport to express, matters of fact. Once this distinction is clear, the nature of truth is supposed to be plain. (shrink)

Even though for Hegel the historian rethinks, positions not as past but as necessary stages in his own philosophical development, the history of philosophy remains external to philosophy proper since a genius could work out from the beginning the stages in the Idea's progress. Hegel's critical history allocates space according to philosophical, not historical considerations, saying little about historical contexts. Non-Hegelians also emphasize assessment more than narration, and all historians of the arts and sciences must make judgments of both importance (...) and value. The history of philosophy, however, has become more historical; assessment requires understanding a philosopher's meaning through his historical situation. (shrink)
