All the evils that men cause to each other because of certain desires, or opinions or religious principles, are rooted in ignorance. [All hatred would come to an end] when the earth was flooded with the knowledge of God.
MaimonidesThe more necessary a thing is for living beings, the more easily it is found and the cheaper it is; the less necessary it is, the rarer and dearer it is.
MaimonidesKnow that for the human mind there are certain objects of perception which are within the scope of its nature and capacity; on the other hand, there are, amongst things which actually exist, certain objects which the mind can in no way and by no means grasp: the gates of perception are closed against it.
