Duties of the Heart
(2) To know and clearly realize that the Creator is watching him, and neither one's private or public conduct is hidden from Him, nor his innermost being or outer appearance. He also knows whether a man's trust in Him is with a sincere heart or not, as the verse says "G-d knows the thoughts of the heart, that they are vain" (Tehilim 94:11) and "Does not He that tests the heart understand it?" (Mishlei 24:12), and "You alone know the hearts of all men" (Melachim I 8:39).
Duties of the Heart
Therefore, my brother, bring yourself to an accounting on this matter and do not be swayed by your evil inclination. Do not consent with your base desires when using your intellect and understanding in this . Put to heart the Creator's observing your making an accounting with yourself in your inner thoughts and let your intent be for the sake of His Name. Carefully think through it for His honor, out of shame of His observing you on it, as written "The L-ord knows the thoughts of man, that they are vanity" (Tehilim 94:11).
Guide for the Perplexed
I will now show you the meaning of these arguments, but first I will point out how the opponents to the words of the Prophets misunderstood this passage. Many years ago some intelligent co-religionists—they were physicians-told me that they were surprised at the words of David; for it would follow from his arguments that the Creator of the mouth must eat and the Creator of the lungs must cry; the same applies to all other organs of our body. You who study this treatise of mine, consider how grossly they misunderstood David’s arguments. Hear now what its true meaning is: He who produces a vessel must have had in his mind an idea of the use of that instrument, otherwise he could not have produced it. If, e.g., the smith had not formed an idea of sewing and possessed a knowledge of it, the needle would not have had the form so indispensable for sewing. The same is the case with all instruments. When some philosopher thought that God, whose perception is purely intellectual, has no knowledge of individual things, which are perceivable only by the senses, David takes his argument from the existence of the senses, and argues thus:—If the sense of sight had been utterly unknown to God, how could He have produced that organ of the sense of sight? Do you think that it was by chance that a transparent humour was formed, and then another humour with certain similar properties, and besides a membrane which by accident had a hole covered with a hardened transparent substance? in short, considering the humour of the eye, its membranes and nerves, with their well-known functions, and their adaptation to the purpose of sight, can any intelligent person imagine that all this is due to chance? Certainly not; we see here necessarily design in nature, as has been shown by all physicians and philosophers; but as nature is not an intellectual being, and is not capable of governing [the universe], as has been accepted by all philosophers, the government [of the universe], which shows signs of design, originates, according to the philosophers, in an intellectual cause, but is according to our view the result of the action of an intellectual being, that endows everything with its natural properties. If this intellect were incapable of perceiving or knowing any of the actions of earthly beings, how could He have created, or, according to the other theory, caused to emanate from Himself, properties that bring about those actions of which He is supposed to have no knowledge? David correctly calls those who believe in this theory brutes and fools. He then proceeds to explain that the error is due to our defective understanding: that God endowed us with the intellect which is the means of our comprehension, and which on account of its insufficiency to form a true idea of God has become the source of great doubts: that He therefore knows what our defects are, and how worthless the doubts are which originate in our faulty reasoning. The Psalmist therefore says: “He who teaches man knowledge, the Lord, knoweth the thoughts of man that they are vanity” (ibid. 94:10-11).
