Nothing is necessitated whose opposite is possible. - Gottfried Wilhelm Leibniz

Gott sah unendlich viele Welten als möglich vor sich; aber aus diesen unendlich vielen wählte er die wirkliche als die beste.

But in the treasures of divine wisdom, that is, in the hidden God and (which comes to the same) in the universal harmony of the world, a profundity (bathos) is latent, which contains the reasons why the actual series of the universe, comprehending the events we admire and the judgements we worship, has been chosen by God as the best and as preferable to all others.

La nature ne fait jamais des sauts.
