One should see the world, and see himself as a scale with an equal balance of good and evil. When he does one good deed the scale is tipped to the good - he and the world is saved. When he does one evil deed the scale is tipped to the bad - he and the world is destroyed.
Maimonides

You must accept the truth from whatever source it comes.
Maimonides

No disease that can be treated by diet should be treated with any other means.
Maimonides

Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime.
Maimonides

Further, there are things of which the mind understands one part, but remains ignorant of the other; and when man is able to comprehend certain things, it does not follow that he must be able to comprehend everything.
Maimonides

Do not imagine that what we have said of the insufficiency of our understanding and of its limited extent is an assertion founded only on the Bible: for philosophers likewise assert the same, and perfectly understand it,- without having regard to any religion or opinion.
Maimonides

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.
Maimonides
