The soul is something which contains the body. The body doesn't contain the soul. The soul, if we put it into modern language, is the entire complex of relationships in whose context this organism exists.
Yet simple souls, their faith it knows no stint:
Things least to be believed are most preferred.
All counterfeits, as from truth's sacred mint,
Are readily believed if once put down in print
The hottest places in hell are reserved for those who, in time of great moral crisis, maintain their neutrality.
[This miserable mode
Maintain the melancholy souls of those
Who lived withouten infamy or praise.]
So, if we must give a general formula applicable to all kinds of soul, we must describe it as the first actuality [entelechy] of anatural organized body.
It is so much more difficult to live with one's body than with one's soul. One's body is so much more exacting: what it won't have it won't have, and nothing can make bitter into sweet.
The desire to serve the common good must without fail be a requisite of the soul, a necessity for personal happiness; if it issuesnot from there, but from theoretical or other considerations, it is not at all the same thing.
