For a truth, once established by proof, does neither gain force nor certainty by the consent of all scholars, nor lose by the general dissent.
Maimonides (1135-1204) Spanish Jewish philosopher, scholar, astronomer, physician [Moses ben Maimon, Rambam, רמב״ם]
Guide for the Perplexed, Part 2, ch. 15 (c. 1190) [tr. Friedlander (1885)]

Alternate translation:
For when something has been demonstrated, the correctness of the matter is not increased and certainty regarding it is not strengthened by the consensus of all men of knowledge with regard to it. Nor could its correctness be diminished and certainty regarding it be weakened even if all the people on earth disagreed with it.
[tr. Pines (1963)]
Quotations by:
Maimonides
If I had omitted setting down something of that which has appeared to me as clear, so that the knowledge would perish when I perish, as is inevitable, I should have considered that conduct as extremely cowardly with regard to you and everyone who is perplexed. It would have been, as it were, robbing one who deserves the truth of the truth, or grudging an heir his inheritance. And both those traits are blameworthy.
Maimonides (1135-1204) Spanish Jewish philosopher, scholar, astronomer, physician [Moses ben Maimon, Rambam, רמב״ם]

Alternate translation:
But if, on the other hand, I were to abstain from writing on this subject, according to my knowledge of it, when I die, as I shall inevitably do, that knowledge would die with me, and I would thus inflict great injury on you and all those who are perplexed. I would then be guilty of withholding the truth from those to whom it ought to be communicated, and of jealously depriving the heir of his inheritance. I should in either case be guilty of gross misconduct.
[tr. Friedlander (1885)]
Do not consider it proof just because it is written in books, for a liar who will deceive with his tongue will not hesitate to do the same with his pen. They are utter fools who accept a thing as convincing proof simply because it is in writing.
Maimonides (1135-1204) Spanish Jewish philosopher, scholar, astronomer, physician [Moses ben Maimon, Rambam, רמב״ם]
Iggeret Teman, “Responsa”
We are obligated to be more scrupulous in fulfilling the commandment of charity than any other positive commandment because charity is the sign of a righteous man, the seed of Abraham our Father.

As quoted in Isadore Twersky, ed., A Maimonides Reader (1972), and the most common English translation. Alternate translation:
We must be especially careful to observe the mitzvah of tzedakah, more so than any other positive mitzvah, for tzedakah is a sign of the righteous [tzadik] lineage of Abraham, our father.
[tr. Meszler (2003)]

It should not be believed that all beings exist for the sake of man. On the contrary, all the other beings too have been intended for their own sakes and not for the sake of something else.

It is of great advantage that man should know his station, and not erroneously imagine that the whole Universe exists only for him.
