 With these general considerations in place, let us examine the historical role that the Principle has played. The term “Principle of Sufficient Reason [principe de raison suffisante/principium reddendae rationis]” was coined by Leibniz, though Spinoza is thought by many scholars to have preceded Leibniz in appreciating the importance of the Principle and placing it at the center of his philosophical  system.[2]  The Principle seems at first sight to have a strong intuitive appeal—we always ask for explanations—yet it is taken by many to be too bold and expensive due to the radical implications it seems to yield. Among the alleged consequences of the Principle are: the Identity of Indiscernibles, necessitarianism, the relativity of space and time, the existence of a self-necessitated Being (i.e., God), and the Principle of Plenitude.
