An ignorant man believes that the whole universe only exists for him: as if nothing else required any consideration. If, therefore, anything happens to him contrary to his expectation, he at once concludes that the whole universe is evil. If, however, he would take into consideration the whole universe, form an idea of it, and comprehend what a small portion he is of the Universe, he will find the truth. There are many ... passages in the books of the prophets expressing the same idea.

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.

You must accept the truth from whatever source it comes.

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.

He, however, who begins with Metaphysics, will not only become confused in matters of religion, but will fall into complete infidelity.

He who does not understand that a dead lion is more alive than a living dog will remain a dog.

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.
