Quote of the Day: "Is it not worthy of tears that, when the number of worlds is infinite, we have not yet become lords of a single one?" is a thought-provoking saying attributed to Alexander the Great and preserved by the ancient Greek biographer and philosopher Plutarch in Moralia. The quote takes on added significance on July 20, traditionally observed as the birth anniversary of Alexander the Great, who was born in 356 BC. It reflects the extraordinary ambition of one of history's greatest military leaders while raising timeless questions about the nature of human desire, achievement and the limits of power.
