A Quote by Immanuel Kant

All the interests of my reason, speculative as well as practical, combine in the three following questions: 1. What can I know? 2. What ought I to do? 3. What may I hope?
Those who incline to very strictly utilitarian views may perhaps feel that the peculiar powers of the Analytical Engine bear upon questions of abstract and speculative science rather than upon those involving everyday and ordinary human interests.
In practical matters the end is not mere speculative knowledge of what is to be done, but rather the doing of it. It is not enough to know about Virtue, then, but we must endeavor to possess it, and to use it, or to take any other steps that may make.
Three things are necessary for the salvation of man: to know what he ought to believe; to know what he ought to desire; and to know what he ought to do.
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.
What can I know? What ought I to do? What may I hope?
Thus the same object may supply a practical perception to one person and a speculative one to another, or the same person may perceive it partly practically and partly speculatively.
Evil is uncertain in the same degree as good, and for the reason that we ought not to hope too securely, we ought not to fear with to much dejection.
The key isn't winning -- or losing, it's making the attempt. I may never be what I ought to be, want to be -- but how will I know unless I try? Sure, it's scary, but what's the alternative? Stagnation - A safer, more terrible form of death. Not of the body, but of the spirit. An animal knows what it is, and accepts it. A man may know what he is -- but he questions. He dreams. He strives. Changes. Grows.
When a truth is necessary, the reason for it can be found by analysis, that is, by resolving it into simpler ideas and truths until the primary ones are reached. It is this way that in mathematics speculative theorems and practical canons are reduced by analysis to definitions, axioms and postulates.
We shall do well ever to remember, that Christianity is not a mere speculative theory, that is to inform the mind; but a great practical lesson, to renew the heart, and to bring us back to the state from whence we are fallen.
The reason I don't like interviews is that I seem to react violently to personal questions. If the questions are about the work, I try to answer them. When they are about me, I may answer or I may not, but even if I do, if the same question is asked tomorrow, the answer may be different.
I think the fun of following the movie box office and stocks is very similar to the fun of sports - all three combine passion and unpredictability.
Science usually operates in sort of three modes, things that are well established, we know what we're talking about, more highly confident. There are competing explanations, we have a pretty good idea, but we're not sure. And then things are speculative.
One minute. You know nothing about him. He probably has his own joys and interests- wife, children, snug little home. That's where we practical fellows'- he smiled-'are more tolerant than you intellectuals. We live and let live, and assume that things are jogging on fairly well elsewhere, and that the ordinary plain man may be trusted to look after his own affairs.
Here are the three great questions which in life we have over and over again to answer: Is it right or wrong? Is it true or false? Is it beautiful or ugly? Our education ought to help us to answer these questions.
Well, Australians should speak for the national interests of Australia, and whatever role former Australian prime ministers may have, one of the things you do is speak frankly about the country as you see the country's best interests, you know?
