The error of the ignorant goes so far as to say that God's power is insufficient, because he has given to this Universe the properties which they ima… - Moshe ben Maimon

I agree with Aristotle as regards all other living beings and à fortiori as regards plants and all the rest of earthly creatures. For I do not believe that it is through Divine Providence that a certain leaf drops, nor do I hold that when a certain spider catches a certain fly, that this is a direct result of a special decree and will of God in that moment; it is not by a particular Divine decree that the spittle of a certain person moved, fell on a certain gnat in a certain place, and killed it; nor is it by the direct will of God that a certain fish catches and swallows a certain worm on the surface of the water. In all these cases the action is... entirely due to chance, as taught by Aristotle.

The theory that Divine Providence does not extend to man, and that there is no difference between man and other animals, implies very bad notions about God; it disturbs all social order, removes and destroys all the moral and intellectual virtues of man.

Those who are ignorant and perverse in their thought are constantly in trouble and pain, because they cannot get as much of the superfluous things as a certain other person possesses. They as a rule expose themselves to great dangers... for the purpose of obtaining that which is superfluous and not necessary. When they thus meet with the consequences of the course which they adopt, they complain of the decrees and the judgements of God; they begin to blame the time, and wonder at the want of justice in its changes; that it has not enabled them to acquire great riches... for the purpose of driving themselves to voluptuousness beyond their capacities, as if the whole Universe existed only for the purpose of giving pleasure to these low people.
