Men frequently think that the evils in the world are more numerous than the good things; many sayings and songs of the nations dwell on this idea. ..… - Moshe ben Maimon

You know from the repeated declarations in the Law that the principal purpose of the whole Law was the removal and utter destruction of idolatry, and all that is connected therewith, even its name, and everything that might lead to any such practices, e.g., acting as a consulter with familiar spirits, or as a wizard, passing children through the fire, divining, observing the clouds, enchanting, charming, or inquiring of the dead. The law prohibits us to imitate the heathen in any of these deeds, and a fortiori to adopt them entirely. It is distinctly said in the Law that everything which idolaters consider as service to their gods, and a means of approaching them, is rejected and despised by God... Thus all precepts cautioning against idolatry, or against that which is connected therewith, leads to it, or is related to it, are evidently useful.

This [fourth] theory likewise implies contradictions and absurdities. The absurdities are these: The fact that some persons are born with defects, although they have not sinned previously, is ascribed to the wisdom of God, it being better for those persons to be in such a condition than to be in a normal state, though we do not see why it is better; and they do not suffer thereby any punishment at all, but, on the contrary, enjoy God's goodness. In a similar manner the slaughter of the pious is explained as being for them the source of an increase in reward in future life. They go even further in their absurdities.

Consider in how many ways His knowledge is distinguished from ours according to all the teaching of every revealed religion. First, His knowledge is one, and yet embraces many different kinds of objects. Secondly, it is applied to things not in existence. Thirdly, it comprehends the infinite. Fourthly, it remains unchanged, though it comprises the knowledge of changeable things; whilst it seems that the knowledge of a thing that is to come into existence is different from the knowledge of the thing when it has come into existence; because there is the additional knowledge of its transition from a state of potentiality into that of reality. Fifthly, according to the teaching of our Law, God's knowledge of one of two eventualities does not determine it, however certain that knowledge may be concerning the future occurrence of the one eventuality.
