An alternative perspective that places Columbus in context, relative to the simplistic Left-dominant anti-occidental prejudices, was provided by Glenn Reynolds, from the book "Admiral of the Ocean Sea : A Life of Christopher Columbus" by Samuel Eliot Morison he with a salient passage referencing the early Euro-malaise: At the end of 1492 most men in Western Europe felt exceedingly gloomy about the future. Christian civilization appeared to be shrinking in area and dividing into hostile units as its sphere contracted. For over a century there had been no important advance in natural science and registration in the universities dwindled as the instruction they offered became increasingly jejune and lifeless. Institutions were decaying, well-meaning people were growing cynical or desperate, and many intelligent men, for want of something better to do, were endeavoring to escape the present through studying the pagan past. . . .

Yet, even as the chroniclers of Nuremberg were correcting their proofs from Koberger's press, a Spanish caravel named Nina scudded before a winter gale into Lisbon with news of a discovery that was to give old Europe another chance. In a few years we find the mental picture completely changed. Strong monarchs are stamping out privy conspiracy and rebellion; the Church, purged and chastened by the Protestant Reformation, puts her house in order; new ideas flare up throughout Italy, France, Germany and the northern nations; faith in God revives and the human spirit is renewed. The change is complete and startling: "A new envisagement of the world has begun, and men are no longer sighing after the imaginary golden age that lay in the distant past, but speculating as to the golden age that might possibly lie in the oncoming future."
Reynolds goes on to further to notice that an article by Jim Bennett has identified the origin of the characteristic y negativity of the Academic Left: "This is primarily an effect of the Calvinist Puritan roots of American progressivism. Just as Calvinists believed in the centrality of the depravity of man, with the exception of a miniscule contingent of the Elect of God, their secularized descendants believe in the depravity and cursedness of Western civilization, with their own enlightened selves in the role of the Elect."
It answers some of the same issues I have with my academic-oriented Calvinist Leftist parents anyhow, and links to those intellectual theologies of "original sin."
