Immanuel Kant was a great philosopher of the ‘Enlightenment Era’, during the late 18th century. Kant was best known for his contributions to philosophy. Immanuel questioned reality by arguing that we only believe in the things that we know about and are sure to exist. But in reality, there are numerous things that exist, yet stay unknown to us. His philosophy revolved around the Ethics and Morals that affect our reasoning and judgement. Most of his ideologies were summed up in his three major books, ‘Critique of Pure Reason’, ‘Critique of Practical Reason’ and ‘Critique of Judgment’. Although Kant kept himself away from religion, he well understood the prominence of religion in human life. His mission was to replace religious authority with human intelligence and his ideologies are well reflected in his sayings and quotations. His observations and thoughts on several issues became popular quotes over time. Here is a compilation of best quotes by Immanuel Kant.
