Scientists ignorant of history are not so much condemned to repeat it, as to be confused and unenterprising. - Stephen Jay Gould

History is also a hard taskmaster, for she covers her paths by erasing so much evidence from her records —

If I choose to impose individual blame for all past social ills, there will be no one left to like in some of the most fascinating periods of our history. For example […] if I place every Victorian anti-Semite beyond the pale of my attention, my compass of available music and literature will be pitifully small. Though I hold no shred of sympathy for active persecution, I cannot excoriate individuals who acquiesced passively in a standard societal judgment. Rail instead against the judgment, and try to understand what motivates men of decent will.

Creative thought in science is exactly this - not a mechanical collection on of facts and intuition, bias, and insight from other fields. Science, at its best, interposes human judgement and ingenuity upon all proceedings. It is, after all (although we sometimes forget it), practiced by humans.
