Now the soul is in some way attached to the pleasant things of life through the senses of the body. Through the eyes it delights in material beauty, through the ears it inclines to melodious sounds, and so it is also affected by smell, taste, and touch, as nature has disposed to be proper to each. Hence, as it is attached to the pleasant things of life through the sensible faculty as if by a nail, it is hard to turn away from them. It has grown up together with these attachments much in the same way as the shellfish and snails are bound to their covering of clay; and so it is slow to make such movements, since it drags along the whole burden of a lifetime. As such is its condition, the soul is easily captured by its persecutors with the threat of confiscation of property or loss of sonic other things that are coveted in this life; and so it gives in easily, and yields to the power of its persecutor.
