“If teleological study of the world is philosophy, and if the Law commands such a study, then the Law commands philosophy.”

“After logic we must proceed to philosophy proper. Here too we have to learn from our predecessors, just as in mathematics and law. Thus it is wrong to forbid the study of ancient philosophy. Harm from it is accidental, like harm from taking medicine, drinking water, or studying law.”

“Asked what he gained from philosophy, he answered, "To do without being commanded what others do from fear of the laws."”

“A Freedom fighter, administrator, and a statesman, attained the status of an internationally acclaimed intellectual in the fields of international relations, rule of law, philosophy, and comparative study of religions.”

“In Judaism, there are 613 biblical commandments, and the Talmud says that the chief commandment of all is study.”

“Since the word "knowledge" occurs in my general title… I am going to be talking about epistemology, although I prefer to use the eighteenth-century, indeed, medieval phrase, "natural philosophy."… that enterprise of the human mind which attempts to trace lawfulness to nature, dead and living, but which is not directed to specific inquiries into how this or that law works. Philosophy in the sense in which I practice it, natural philosophy, is concerned with lawfulness rather than with laws and the general nature of laws rather than with the specific structure of this or that law. Natural philosophy was one of the three topics (moral philosophy and metaphysical philosophy were the others) to which one graduated in medieval universities after having studied the seven liberal arts.
I believe that we need to review the whole of our natural philosophy in the light of scientific knowledge that has arisen in the last fifty years.”

“Philosophy stands in the same relation to the study of the actual world as masturbation to sexual love.”

“To study philosophy is nothing but to prepare one’s self to die.”

“Trying to command life without studying one's own mind is like trying to play the piano without studying music.”

“I must study politics and war, that our sons may have liberty to study mathematics and philosophy. Our sons ought to study mathematics and philosophy, geography, natural history and naval architecture, navigation, commerce and agriculture in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry and porcelain.”
