It has been my experience that those with no vices have very few virtues.
They just haven’t lived enough to have enough true virtues.
For living, truly living, means encountering vices which hold you so dearly that you never leave them. And continuing to live with those vices is what develops true virtues.
A man cannot be considered strong unless he’s been battle tested. And a person cannot have true virtues unless they’ve been tested with vices they cannot resist.
This is what I know.
