“All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.” So wrote Immanuel Kant in his Critique of Pure Reason, one of the most influential philosophy books of all time. Kant is also the philosopher credited for finally overcoming the opposition between empiricism and rationalism in epistemology, as he realized that neither position, by itself, is sufficient to account for human knowledge.
Immanuel Kant (1724-1804) was an 18th century philosopher, one of the earliest philosophers belonging to the enlightenment tradition, and often considered the father of German Idealism. Kant is remembered today more for his moral philosophy than his contributions to metaphysics and epistemology (Rohlf 2010). His contributions to the field of life-extension, however, remain almost completely unexplored, despite the fact that certain claims made in his Theory of Ethics arguably qualify him as a historical antecedent of the contemporary social movement and academic discipline of life-extension.
