From Albert Schweitzer
"The lot of the many is to have as a profession,
for the earning of their living and the satisfaction
of society's claim on them, a more or less soulless labor
in which they can give out little or nothing of their human qualities,
because in that labor they have to be
little better than human machines.
;Yet no one finds himself in the position of having no possible
opportunity of giving himself to others as a human being.
...No fate can prevent a man from giving to others this
direct human service side by side with his lifework.
If so much of such service remains unrealized,
it is because the opportunities are missed."
...Albert Schweitzer...
