Seneca,
Moral letters to Lucilius — Letter 89…
“ Inasmuch, however, as this cannot fall to our lot, we must view philosophy just as men gaze upon the secrets of the firmament. 2. The wise man's mind, to be sure, embraces the whole framework of philosophy, surveying it with no less rapid glance than our mortal eyes survey the heavens; we, however, who must break through the gloom, we whose vision fails even for that which is near at hand, can be shown with greater ease each separate object even though we cannot yet comprehend the universe. I shall therefore comply with your demand, and shall divide philosophy into parts, but not into scraps. ”
