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 imagine cause these great evils, and which do not help all evil-disposed persons to obtain the evil which they seek, and to bring their evil souls to the aim of their desires, though these, as we have shown, are really without limit.

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.

The soul, when accustomed to superfluous things, acquires a strong habit of desiring things which are neither necessary for the preservation of the individual nor for that of the species. This desire is without limit, whilst those which are necessary are few in number and restricted within certain limits; but what is superfluous is without end...

In so far as the soul is a force residing in the body; it has therefore been said that the properties of the soul depend of the condition of the body.

The third class of evils comprise those which everyone causes to himself by his own action. This is the largest class, and is far more numerous than the second class. It is especially of these evils that all men complain,—only few men are found that do not sin against themselves by this kind of evil. ...This class of evil originates in man's vices, such as excessive desire for eating, drinking, and love; indulgence in these things in undue measure, or in improper manner, or partaking of bad food. This course brings diseases and afflictions upon the body and soul alike.

The second class of evils comprises such evils as people cause to each other, when, e.g., some of them use their strength against others. These evils are more numerous than those of the first kind... they likewise originate in ourselves, though the sufferer himself cannot avert them.

Galen, in the third section of his book, "The Use of the Limbs," says correctly that it would be in vain to expect to see living beings formed of the blood of menstruous women and the semen virile, who will not die, will never feel pain, or will move perpetually, or shine like the sun. This dictum of Galen is part of the following more general proposition:—Whatever is formed of matter receives the most perfect form possible in that species of matter; in each individual case the defects are in accordance with that individual matter.

He who thinks he can have flesh and bones without being subject to any external influence, or any accidents of matter, unconsciously wishes to reconcile two opposites, viz., to be at the same time subject and not subject to change. If man were never subject to change there could be no generation; there would be one single being, but no individuals forming a species.

In accordance with the divine wisdom, genesis can only take place through destruction, and without destruction of the individual members of the species the species themselves would not exist permanently. Thus the true kindness, and beneficence, and goodness of God is clear.

The first kind of evil is that which is caused to man by the circumstance that he is subject to genesis and destruction, or that he possesses a body.
