A Quote by Bertrand Russell

In the first place a philosophical proposition must be general. It must not deal specially with things on the surface of the earth, or within the solar system, or with any other portion of space and time. . . . This brings us to a second characteristic of philosophical propositions, namely that they must be a priori. A philosophical proposition must be such as can neither be proved nor disproved by empirical evidence. . . . Philosophy, if what has been said is correct, becomes indistinguishable from logic as that word has now come to be used.

Logical investigations can obviously be a useful tool for philosophy. They must, however, be informed by a sensitivity to the philosophical significance of the formalism and by a generous admixture of common sense, as well as a thorough understanding both of the basic concepts and of the technical details of the formal material used. It should not be supposed that the formalism can grind out philosophical results in a manner beyond the capacity of ordinary philosophical reasoning. There is no mathematical substitute for philosophy.

Saul Kripke

Philosophy aims at the logical clarification of thoughts. Philosophy is not a body of doctrine but an activity. A philosophical work consists essentially of elucidations. Philosophy does not result in 'philosophical propositions', but rather in the clarification of propositions. Without philosophy thoughts are, as it were, cloudy and indistinct: its task is to make them clear and to give them sharp boundaries.

Ludwig Wittgenstein

We must have a new mythology, but it must place itself at the service of ideas, it must become a mythology of reason. Mythology must become philosophical, so that the people may become rational, and philosophy must become mythological, so that philosophers may become sensible. If we do not give ideas a form that is aesthetic, i.e., mythological, they will hold no interest for people.

Georg Wilhelm Friedrich Hegel

Experience has two things to teach. The first is that we must correct a great deal and the second, that we must not correct too much.

Eugene Delacroix

If you read philosophical texts of the tradition, you'll notice they almost never said 'I,' and didn't speak in the first person. From Aristotle to Heidegger, they try to consider their own lives as something marginal or accidental. What was essential was their teaching and their thinking. Biography is something empirical and outside, and is considered an accident that isn't necessarily or essentially linked to the philosophical activity or system.

Jacques Derrida

Man must at all costs overcome the Earth's gravity and have, in reserve, the space at least of the Solar System. All kinds of danger wait for him on the Earth. . . . We have said a great deal about the advantages of migration into space, but not all can be said or even imagined.

Konstantin Tsiolkovsky

To make our position clearer, we may formulate it in another way. Let us call a proposition which records an actual or possible observation an experiential proposition. Then we may say that it is the mark of a genuine factual proposition, not that it should be equivalent to an experiential proposition, or any finite number of experiential propositions, but simply that some experiential propositions can be deduced from it in conjunction with certain other premises without being deducible from those other premises alone.

A.J. Ayer

The terminology of philosophical art is coercive: arguments are powerful and best when they are knockdown, arguments force you to a conclusion, if you believe the premisses you have to or must believe the conclusion, some arguments do not carry much punch, and so forth. A philosophical argument is an attempt to get someone to believe something, whether he wants to beleive it or not. A successful philosophical argument, a strong argument, forces someone to a belief.

Robert Nozick

Unlike the interference of ordinary interest, power, or prejudice, which touches philosophy only at its outskirts and becomes at most a matter for philosophical tactics, the claim of revelation to the highest truth touches philosophy at its core and must affect its whole strategy.

Hans Jonas

The system becomes logically closed when each of the logical implications which can be derived from any one proposition within the system finds its statement in another proposition in the same system.

Talcott Parsons

My first degree was in mathematics. That was great, but it didn't help with many of the things that puzzled me. I became a philosopher because I wanted to understand everything, especially those things that didn't make sense. And that has continued to be my philosophical motivation. That's one reason I have such a roving philosophical eye - once I have figured out a philosophical topic to my satisfaction, I find myself moving on to new problems.

David Papineau

Without doubt, if we are to go back to that ultimate, integral experience, unwarped by the sophistications of theory, that experience whose elucidation is the final aim of philosophy, the flux of things is one ultimate generalization around which we must weave our philosophical system.

Alfred North Whitehead

Eventually, Aristotle appeared among the Greeks. He improved the methods of logic and systematized its problems and details. He assigned to logic its proper place as the first philosophical discipline and the introduction to philosophy. Therefore he is called the First Teacher.

Ibn Khaldun

I have often noticed that when people come to understand a mathematical proposition in some other way than that of the ordinary demonstration, they promptly say, "Oh, I see. That's how it must be." This is a sign that they explain it to themselves from within their own system.

Georg C. Lichtenberg

It is perfectly true, as philosophers say, that life must be understood backwards. But they forget the other proposition, that it must be lived forwards.

Soren Kierkegaard

To make a revolution, people must not only struggle against existing institutions. They must make a philosophical/ spiritual leap and become more 'human' human beings. In order to change/ transform the world, they must change/ transform themselves.
