Logic Quotes

“To make music means to express human intelligence by sonic means. This is intelligence in its broadest sense, which includes not only the peregrinations of pure logic but also the "logic" of emotions and intuition. My musical techniques, although often rigorous in their internal structure, leave many openings through which the most complex and mysterious factors of the intelligence may penetrate.”

“The Libertarians, of whom I'm rather fond, are running Harry Browne. Libertarians are, just as they claim, principled and consistent - they believe in individual liberty. Commendable as they are, and despite their reliability as allies in civil liberties struggles, you may notice that Libertarians sometimes prove that a foolish consistency is the hobgoblin of little minds, and that there is a difference between logic and wisdom.”

“The maxim is, that whatever can be affirmed (or denied) of a class, may be affirmed (or denied) of everything included in the class. This axiom, supposed to be the basis of the syllogistic theory, is termed by logicians the dictum de omni et nullo.”

“Let the Spirit be lacking, and there may be wisdom of words, but not the wisdom of God; the powers of oratory, but not the power of God; the demonstration of argument and the logic of the schools, but not the demonstration of the Holy Spirit, the all-convincing logic of His lightning flash, such as convinced Saul before the Damascus gate. When the Spirit was outpoured the disciples were all filled with power from on high, the most unlettered tongue could silence gainsayers, and with its new fire burn its way through obstacles as flames fanned by mighty winds sweep through forests.”

“In other words, the propositions of philosophy are not factual, but linguistic in character - that is, they do not describe the behaviour of physical, or even mental, objects; they express definitions, or the formal consequences of definitions. Accordingly we may say that philosophy is a department of logic. For we will see that the characteristic mark of a purely logical enquiry, is that it is concerned with the formal consequences of our definitions and not with questions of empirical fact.”

“Be grateful simply for being alive. When you are grateful for life, pure and simple, your life becomes one you can be grateful for. That may strike you as circular or even backward logic, but your attitude really does have an effect on how things work out. When you can't change your life any other way, you can still change your attitude. When you do, your life changes. You find more chances to love, and you will be surprised to see how much more love is returned to you.”

“This is the perpetual and pitiful tragedy of the practical man in practical affairs. He always begins with a flourish of contempt for what he calls theorizing and what people who can do it call thinking. He will not wait for logic-that is, in the most exact sense, he will not listen to reason. It will therefore appear to him an idle and ineffectual proceeding to say that there is a reason for his present failure. Nevertheless, it may be well to say it, and to try and make it clear even to him.”
