La plupart des évènements ont des causes aussi petites. Nous les ignorons, parce que la plupart des historiens les ont ignorées eux-mêmes, ou parce qu’ils n’ont pas eu d’yeux pour les appercevoir. Il est vrai qu’à cet égard l’esprit peut réparer leurs omissions : la connoissance de certains principes supplée facilement à la connoissance de certains faits.

The Idea of Progress: An Inquiry Into Its Origin and Growth (1921)
Kontext: Science has been advancing without interruption during the last three of four hundred years; every new discovery has led to new problems and new methods of solution, and opened up new fields for exploration. Hitherto men of science have not been compelled to halt, they have always found ways to advance further. But what assurance have we that they will not come up against impassable barriers?... Take biology or astronomy. How can we be sure that some day progress may not come to a dead pause, not because knowledge is exhausted, but because our resources for investigation are exhausted... It is an assumption, which cannot be verified, that we shall not reach a point in our knowledge of nature beyond which the human intellect is unqualified to pass.

The Ethics of Belief (1877), The Weight Of Authority
Kontext: We have no right to believe a thing true because everybody says so unless there are good grounds for believing that some one person at least has the means of knowing what is true, and is speaking the truth so far as he knows it. However many nations and generations of men are brought into the witness-box they cannot testify to anything which they do not know. Every man who has accepted the statement from somebody else, without himself testing and verifying it, is out of court; his word is worth nothing at all. And when we get back at last to the true birth and beginning of the statement, two serious questions must be disposed of in regard to him who first made it: was he mistaken in thinking that he knew about this matter, or was he lying?
„Knowledge of the fact differs from knowledge of the reason for the fact.“

Posterior Analytics
— Gottlob Frege, Über Sinn und Bedeutung
The discovery that the rising sun is not new every morning, but always the same, was one of the most fertile astronomical discoveries. Even to-day the identification of a small planet or a comet is not always a matter of course. Now if we were to regard equality as a relation between that which the names 'a' and 'b' designate, it would seem that a = b could not differ from a = a (i.e. provided a = b is true). A relation would thereby be expressed of a thing to itself, and indeed one in which each thing stands to itself but to no other thing.
