"That is better and more valuable which requires fewer, other circumstances being equal, just as that demonstration is better, other circumstances being equal, which necessitates the answering of a smaller number of questions for a perfect demonstration or requires a smaller number of suppositions and premises from which the demonstration proceeds. For if one thing were demonstrated from many and another thing from fewer equally known premisses, clearly that is better which is from fewer because it makes us know quickly, just as a universal demonstration is better than particular because it produces knowledge from fewer premises. Similarly in natural science, in moral science, and in metaphysics the best is that which needs no premisses and the better that which needs the fewer, other circumstances being equal."
"He who performs not practical work nor makes experiments will never attain to the least degree of mastery. But then, O my son, do thou experiment so that thou mayesy acquire knowledge. Scientists delight not in abundance of material; they rejoice only in the excellence of their experimental methods."
"Can all that Optics teach, unfold Thy form to please me so, As when I dreamed of gems and gold Hid in thy radiant bow? When Science from Creations face Enchantments veil withdraws, What lovely visions yield their place To cold material laws!"
"Scientific Knowledge is a mode of conception dealing with universals and things that are of necessity; and demonstrated truths and all scientific knowledge (since this involves reasoning) are derived from first principles. Consequently the first principles from which scientific truths are derived cannot themselves be reached by Science; nor yet are they apprehended by Art, nor by Prudence. To be matter of Scientific Knowledge a truth must be demonstrated by deduction from other truths; while Art and Prudence are concerned only with things that admit of variation. Nor is Wisdom the knowledge of first principles either: for the philosopher has to arrive at some things by demonstration."
"Im not anti-science, Im anti the way science is sometimes used."
"Modern science explicitly and emphatically rejects teleology."
"Modern science will continue to be blindly destructive as long as its operations are determined by the anarchism of market economic forces. The problem to be solved is whether science, technology, and industry can be brought under genuinely democratic control in the context of a global planned economy, so that all of us can collectively put our hard-won scientific knowledge to mutually beneficial use. I am confident it can be accomplished, but will it? If so, there is reason for optimism. If not... well, to paraphrase Keynes, "in the not-so-long run were all dead."
