In 1684, Gottfried Wilhelm Leibniz developed his philosophical work, Monadology, which proposed a unique view of the universe composed of infinite, indivisible entities called 'monads.' This concept not only contributed to the field of metaphysics but also paralleled his advancements in calculus. Leibniz's ideas on monads emphasized the interconnectedness of all things, influencing later philosophical thought and laying groundwork for discussions on perception and reality.

Leibniz's Monadology introduced ideas of optimism and interconnectedness, which permeated literature and inspired poets like Voltaire to critique such philosophies. This tension between hope and skepticism became a recurring theme in poetry, shaping the discourse on human existence.
