Its issue is metaphysics, which yields the most general first principles of things. Unfortunately, it is not popular for several reasons.

             David Hume, seemingly striking the anvil between the descent of the popular philosophical pursuits of the day and the birth of Newtonian Science, was an outstanding philosopher – not because of his achievements, but because of his mode. He was a dedicated historian particularly to Great Britain, and compiling various volumes, he maintained a soldier's strife, but ironically died the year of 1776. His closest critics called him irrational, a man of positivism, and worst, an atheist, which was near damnable in his days, but a commitment to his pursuit of empirical truths have come to revere his name since.
