Oh Idealistic/Optimistic Scientists of the 18th century...

"The rapid progress true science now makes occasions my regretting sometimes that I was born too soon. It is impossible to imagine the height to which may be carried, in a thousand years, the power of man over matter...all diseases may be sure means be prevented or cured, not excepting even that of old age...O that moral science were in as fair a way of improvement, that men would cease to be wolves to one another, and that human beings would at length learn what they improperly call humanity."

-Benjamin Franklin (1706–1790)(1706-01-17)
