'Tis new to thee

From The Plagues of the Mind by Bruce S. Thorton, page 86.

Without that contextualizing distance we fall into the trap of what Gary Saul Morson calls "chronocentricism," the arrogant "temporal egotism" that judges everything by the standards and "knowledge" of the present, as though our accidental lateness confers on us greater wisdom instead of knowledge of a greater number of facts. But just as objects nearer to us appear bigger than they actually are, and we obliterate the sun with a thumb, so the ideas of the present take on an importance and heft that they might not deserve. Forgetting the wisdom of the Preacher that there is nothing new uunder the sun, we continually cry out like Shakespeare's Miranda "O brave new world!" and seldom hear the older, wiser Prospero snort, "'Tis new to thee."
