Come, therefore, all ye reasonings of counsellors, in some way or the other to the assembly of the soul; come, all ye who meditate the destruction of justice and of all virtue, and let us consider carefully how we may attain to the end which we desire. Now of success in this matter these will be the most established foundations: to give to things without form shape

 Genesis xxvi. 9 

 Exodus ii. 22. 
 
and character, and to distinguish each thing separately with distinct outlines, lest, if they become shaken and lame (though fixed on firm foundations,) and if they have assumed a connection with the nature of a quadrangular shape, (for this is a nature always unshaken), they may then, being established steadily like a building of brick, support even those things which are built upon them.
 Of such a structure as this every mind adverse to God, which we call the king of Egypt (that is to say of the body), is found to be the maker. For Moses represents the mind as rejoicing in the buildings made of brick; for after some being or other made the two substances of water and earth to be the one dry and the other solid, and mingling the two together, for they were easily dissoluble and corruptible, made a third substance to be on the confines of the two, which is called clay, he has never ceased from dissecting this into small portions, giving its own appropriate figure to each of the fragments, in order that they might be very well compacted together, and very suitable to the objects for which they were intended. For in this way what was being made was sure to be very easily perfected.
 Imitating this work, those men who are wicked in their natures, when they mingle the irrational and extravagant impulses of the passions with the most grievous vices, are, in reality, dissecting that which has been combined into various species, and unhappy that they are fashioning them again and reducing them into shape, by means of which the blockade of the soul will be raised on high; these being, in fact, the divisions of the outward sense into seeing, and hearing, and taste, and smell, and touch. Passion, again, is divided into pleasure, and appetite, and fear, and grief; and the universal genus of vices is divided into folly, and intemperance, and cowardice, and injustice, and all the other vices which are akin to or closely connected with them.
