Thomas Aquinas,
Summa Theologiae — Question 123 - OF FORTITUDE…
“ Fortitude is not lacking in courage, for alone she defends the honor of the virtues and guards their behests. She it is that wages an inexorable war on all vice, undeterred by toil, brave in face of dangers, steeled against pleasures, unyielding to lusts, avoiding covetousness as a deformity that weakens virtue ”
