Epictetus,
Epictetus, the Discourses as reported by Arrian…
(1925)
“ The use which we make of the external impressions is our one chief concern, and upon the right kind of use depends exclusively our happiness. In the realm of judgement the truth or falsity of the external impression is to be decided. Here our concern is to assent to the true impression, reject the false, and suspend judgement regarding the uncertain. This is an act of the moral purpose, or free will. ”
