You will certainly not doubt the necessity of studying astronomy and physics, if you are desirous of comprehending the relation between the world and Providence as it is in reality, and not according to imagination.
Be convinced that, if man were able to reach the end without preparatory studies, such studies would not be preparatory but tiresome and utterly superfluous.
WHEN reading my present treatise, bear in mind that by "faith" we do not understand merely that which is uttered with the lips, but also that which is apprehended by the soul, the conviction that the object [of belief] is exactly as it is apprehended. If, as regards real or supposed truths, you content yourself with giving utterance to them in words, without apprehending them or believing in them, especially if you do not seek real truth, you have a very easy task as, in fact, you will find many ignorant people professing articles of faith without connecting any idea with them.
Even the existence of this corporeal element, low as it in reality is, because it is the source of death and all evils, is likewise good for the permanence of the Universe and the continuation of the order of things, so that one thing departs and the other succeeds.
In the realm of Nature there is nothing purposeless, trivial, or unnecessary
You must accept the truth from whatever source it comes.
You know already that most of the lusts and licentiousness of the multitude consist in an appetite for eating, drinking and sexual intercourse.
You will find that there is no other difference of opinion as regards any portions of the Universe, except that the philosophers believe in the Eternity of the Universe and we believe in the Creation. Note this.
You must consider, when reading this treatise, that mental perception, because connected with matter, is subject to conditions similar to those to which physical perception is subject.
For it is said, "You shall strengthen the stranger and the dweller in your midst and live with him," that is to say, strengthen him until he needs no longer fall upon the mercy of the community or be in need.
Know 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.
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.
The business conduct of the disciples of wise men is truthful and faithful.... He does not allow himself to be made a surety or a guarantor and does not accept the power of attorney.... He lends money and is gracious. He shall not take away business from his fellow man.
The key to the understanding and to the full comprehension of all that the Prophets have said is found in the knowledge of the figures, their general ideas, and the meaning of each word they contain.
