This book traces the footsteps of the thinking of Immanuel Kant, an 18th-century German philosopher who grappled with this question for many years through trial and error. In Kant's thought process, there were dialogues and confrontations with the ideas of his contemporaries in the German Enlightenment. Initially, Kant believed that in the realm of uncertainty, it would be best to pursue exploration based on mathematical certainty, like Wolff, Wolffian Baumgarten, and Meier's theory of probability. Around the time of the publication of *Critique of Pure Reason* (first edition 1781), Kant appealed to the standard of whether one could stake one's entire life's happiness in the realm of illusion, based on the idea of moral certainty based on moral laws.
