“Whosoever is miserly with the gift of his knowledge deserves more blame than whosoever is miserly with his money, because the man miserly with his money fears exhausting what he has, but the one miserly with his science is with an object which does not become exhausted with use, and that he would lose nothing in sharing it.”

“If first you rid yourself of hope and fear
You have dismayed the tyrant's wrath:
But whosoever quakes in fear or hope,
Drifting and losing his mastery,
Has cast away his shield, has left his place,
And binds the chain with which he will be bound.”
Nec speres aliquid nec extimescas, exarmaueris impotentis iram; at quisquis trepidus pauet uel optat, quod non sit stabilis suique iuris, abiecit clipeum locoque motus nectit qua ualeat trahi catenam.

“His stated principle is that all knowledge should be at the public disposal. He argues against the hoarding of scientific discoveries, believing that the miserly act of secretion is in itself bound to produce fear and unnecessary caution in the mind of the citizen. Superstitious destruction of the unfamiliar is its most common expression. Prince Badehoff-Fischer argues that in such matters a secret is parallel, if not identical, to a lie. Both occur because one body seeks power over another.”

“Whosoever seeks the truth will not proceed by studying the writings of his predecessors and by simply accepting his own good opinion of them. Whosoever studies works of science must, if he wants to find the truth, transform himself into a critic of everything he reads.”

“Whoever harms his kinship and his neighbors is worse than them. Whosoever returns ill that he receives from them is like them. Whosoever does not return ill done to him is the master, the best and most virtuous amongst all.”

“Whosoever complains of the bad character of another man has revealed the badness of his own character.”

“In scientific subjects, the natural remedy for dogmatism has been found in research. By temperament and training, the research worker is the antithesis of the pundit. What he is actively and constantly aware of is his ignorance, not his knowledge; the insufficiency of his concepts, of the terms and phrases in which he tries to excogitate his problems: not their final and exhaustive sufficiency. He is, therefore, usually only a good teacher for the few who wish to use their mind as a workshop, rather than a warehouse.”

“The superior man, while there is anything he has not studied, or while in what he has studied there is anything he cannot understand, Will not intermit his labor. While there is anything he has not inquired about, or anything in what he has inquired about which he does not know, he will not intermit his labor. While there is anything which he has not reflected on, or anything in what he has reflected on which he does not apprehend, he will not intermit his labor. While there is anything which he has not discriminated or his discrimination is not clear, he will not intermit his labor. If there be anything which he has not practiced, or his practice fails in earnestness, he will not intermit his labor. If another man succeed by one effort, he will use a hundred efforts. If another man succeed by ten efforts, he will use a thousand. Let a man proceed in this way, and, though dull, he will surely become intelligent; though weak, he will surely become strong.”

“Where a man has but one remedy to come at his right, if he loses that he loses his right.”

“Man…. Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived.”
