I don’t let go of concepts—I question them. Then they let go of me.
Byron Katie
If we wish to express our ideas in terms of the concepts synthetic and analytic, we would have to point out that these concepts are applicable only to sentences that can be either true of false, and not to definitions. The mathematical axioms are therefore neither synthetic nor analytic, but definitions. ...Hence the question of whether axioms are a priori becomes pointless since they are arbitrary.
Hans Reichenbach
We are saddled with a culture that hasn't advanced as far as science. Scientific man is already on the moon, and yet we are still living with the moral concepts of Homer. Hence this upset, this disequilibrium that makes weaker people anxious and apprehensive, that makes it so difficult for them to adapt to the mechanism of modern life. ... We live in a society that compels us to go on using these concepts, and we no longer know what they mean. In the future — not soon, perhaps by the twenty-fifth century — these concepts will have lost their relevance. I can never understand how we have been able to follow these worn-out tracks, which have been laid down by panic in the face of nature. When man becomes reconciled to nature, when space becomes his true background, these words and concepts will have lost their meaning, and we will no longer have to use them.
Michelangelo Antonioni
None of the Marxist concepts (literally – not a single one!) matches the logical rules of scientific concepts.
Aleksandr Zinovyev
To new concepts correspond, necessarily, new signs. These we choose in such a way that they remind us of the phenomena which were the occasion for the formation of the new concepts.
David Hilbert
All significant concepts of the modern theory of the state are secularized theological concepts not only because of their historical development—in which they were transferred from theology to the theory of the state, whereby, for example, the omnipotent God became the omnipotent lawgiver—but also because of their systematic structure, the recognition of which is necessary for a sociological consideration of these concepts. The exception in jurisprudence is analogous to the miracle in theology.
