Book VIII · 45
Take me and cast me where thou wilt; for there I shall keep my divine part tranquil, that is, content, if it can feel and act conformably to its proper constitution. Is this [change of place] sufficient reason why my soul should be unhappy and worse than it was, depressed, expanded, shrinking, affrighted? and what wilt thou find which is sufficient reason for this?7
Take me up and cast me where thou wilt. For even there will I keep my 'genius' tranquil, that is, content if in itself and in its activity it follow the laws of its own constitution.
Is this worth while, that on its account my soul should be ill at ease and fall below itself, grovelling, grasping, floundering, affrighted? What could make it worth while?
