"Abraham was the first to teach the Unity of God, to establish the faith, to cause it to remain among coming generations, and to win his fellow-men to his doctrine; as Scripture says of him: "I know him, that he will command," &c. (Gen. xviii. 19)"
Moses ben Maimon, commonly known as Maimonides and also referred to by the Hebrew acronym Rambam, was a Sephardic Jewish rabbi who is widely acknowledged as one of the most prolific and influential Torah scholars of the Middle Ages.

"Having concluded these introductory remarks I proceed to examine those expressions, to the true meaning of which, as apparent from the context, it is necessary to direct your attention.

Maimonides"There is one [disease] which is widespread, and from which men rarely escape. This disease varies in degree in different men … I refer to this: that every person thinks his mind … more clever and more learned than it is … I have found that this disease has attacked many an intelligent person … They … express themselves [not only] upon the science with which they are familiar, but upon other sciences about which they know nothing … If met with applause … so does the disease itself become aggravated."
Maimonides"This must be our belief when we have a correct knowledge of our own self, and comprehend the true nature of everything; we must be content, and not trouble our mind with seeking a certain final cause for things that have none, or have no other final cause but their own existence, which depends on the Will of God, or, if you prefer, on the Divine Wisdom."
Maimonides"He will punish all the evil deeds of men, although they have not been prohibited by a prophet, if common sense warns against them, as e.g., injustice and violence. ...it is distinctly added that he who does a good thing without being commanded, receives nevertheless his reward. The same principle is expressed in all the sayings of our Sages."
