  1. Now and then philosophers invade the field of biological sciences with these beguiling generalizations, which tend to be unproductive, purely verbal solutions lacking in substance. At best, they may prove useful when viewed simply as working hypotheses.

  2. He who marches out of line hears another drum.

  3. Instead of elaborating on accepted principles, let us simply point out that for the last hundred years the natural sciences have abandoned completely the Aristotelian principles of intuition, inspiration, and dogmatism.

  4. As Claude Bernard has pointed out, researchers cannot transcend the determinism of phenomena; instead, their mission is limited to demonstrating the how, never the why, of observed changes. This is a modest goal in the eyes of philosophy, yet an imposing challenge in actual practice.

  5. The severe constraints imposed by determinism may appear to limit philosophy in a rather arbitrary way. However, there is no denying that in the natural sciences — and especially in biology — it is a very effective tool for avoiding the innate tendency to explain the universe as a whole in terms of general laws.

  6. Later, hiding in the latrine from the black boys, I'd take a look at my own self in the mirror and wonder how it was possible that anybody could manage such an enormous thing as being what he was.

  7. Knowing the conditions under which a phenomenon occurs allows us to reproduce or eliminate it at will, therefore allowing us to control and use it for the benefit of humanity. Foresight and action are the advantages we obtain from a deterministic view of phenomena.

  8. There is no doubt that the human mind is fundamentally incapable of solving these formidable problems (the origin of life, nature of matter, origin of movement, and appearance of consciousness). Our brain is an organ of action that is directed toward practical tasks; it does not appear to have been built for discovering the ultimate causes of things, but rather for determining their immediate causes and invariant relationships.

  9. Maybe not you, buddy, but the rest are even scared to open up and laugh. You know, that's the first thing that got me about this place, that there wasn't anybody laughing. I haven't heard a real laugh since I came through that door, do you know that? Man, when you lose your laugh you lose your footing.

  10. In summary, there are no small problems. Problems that appear small are large problems that are not understood (p. 17).

  11. The intellect is presented with phenomena marching in review before the sensory organs. It can be truly useful and productive only when limiting itself to the modest tasks of observation, description, and comparison, and of classification that is based on analogies and differences. A knowledge of underlying causes and empirical laws will then come slowly through the use of inductive methods.

  12. The unique method of reflection indulged in by the Pythagoreans and followers of Plato (and pursued in modern times by Descartes, Fichte, Krause, Hegel, and more recently at least partly by Bergson) involves exploring one’s own mind or soul to discover universal laws and solutions to the great secrets of life.
