• The philosopher of science is not much interested in the thought processes which lead to scientific discoveries; he looks for a logical analysis of the completed theory, including the establishing its validity. That is, he is not interested in the context of discovery, but in the context of justification.

• The essence of knowledge is generalization. That fire can be produced by rubbing wood in a certain way is a knowledge derived by generalization from individual experiences; the statement means that rubbing wood in this way will always produce fire. The art of discovery is therefore the art of correct generalization. ... The separation of relevant from irrelevant factors is the beginning of knowledge.

• El concepto de congruencia en geometría euclidiana no es exactamente el mismo que en geometría no euclidiana. ... "Congruente" significa en geometría euclidiana lo mismo que "determinante del paralelismo", significado que no tiene en geometría no euclidiana.
