History, which interprets the past to understand the present and confront the future is the least rewarding discipline for a dying species.
P. D. Jamesto look back on one's life is to experience the capriciousness of memory. ... the past is not static. It can be relived only in memory, and memory is a device for forgetting as well as remembering. It, too, is not immutable. It rediscovers, reinvents, reorganizes. Like a passage of prose it can be revised and repunctuated. To that extent, every autobiography is a work of fiction and every work of fiction an autobiography.
P. D. JamesOf the four billion life forms which have existed on this planet, three billion, nine hundred and sixty million are now extinct. We don't know why. Some by wanton extinction, some through natural catastrophe, some destroyed by meteorites and asteroids. In the light of these mass extinctions it really does seem unreasonable to suppose that Homo sapiens should be exempt. Our species will have been one of the shortest-lived of all, a mere blink, you may say, in the eye of time.
