Concepts that have proven useful in ordering things easily achieve suc — Concept

"A systematic revolution of basic concepts begins with Einsteinian science. In the very detail of its concepts a relativism of the rational and the empirical is established. Science then undergoes what Nietzche called "an upheaval of concepts," as if the earth, the universe, things, possessed a different structure from the fact that their explanation rests upon new foundations. All rational organization is "shaken" when the fundamental concepts undergo dialectical transformation."

"There are three aspects of thinking as more or less complete stages of it. These are, conception, judgment, and reasoning. They are not to be considered three distinct acts; not even three successive stages. No one of them could occur without each of the others."

"The aim of science is... a comprehension, as complete as possible, of the connection between the sense experiences in their totality, and... the accomplishment of this aim by the use of the minimum of primary concepts and relations."

"Kant says that concept without percepts are empty, percepts without concepts are blind; it would perhaps be truer to say that concepts and percepts are inseparable; and if torn asunder, they are nothing."

"Concepts have meaning only if we can point to objects to which they refer and to rules by which they are assigned to these objects."

"Conception is taking together into one idea the element of meaning common to a number of objects and things. ...Conception is... the simplest act of thinking; it is the apprehension of the universal, as perception is the apperception of the particular. We perceive this man; we conceive man. ...it is universal through its ideal element, or what it points to, not from its existence."
