A quote
No man learns a thing in order that, if necessity arises, he may lie down with composure upon a bed of roses; but he steels his courage to this end,—that he may not surrender his plighted faith to torture, and that, if need be, he may some day stay out his watch in the trenches, even though wounded, without even leaning on his spear; because sleep is likely to creep over men who support themselves by any prop whatsoever. In death there is nothing harmful; for there must exist something to which it is harmful.
