Immanuel Kant, a pivotal Enlightenment philosopher

Immanuel Kant, a pivotal Enlightenment philosopher, is known for quotes emphasizing reason, duty, and human dignity, such as his famous "Dare to think!" (Sapere aude!), urging self-guided understanding, and the

Categorical Imperative: "Act only according to that maxim whereby you can at the same time will that it should become a universal law," highlighting universal moral principles, and the idea to treat humanity "never merely as a means to an end, but always at the same time as an end". Other key quotes touch on the awe of the "starry sky above me and the moral law within me," the link between knowledge and experience, and that "Science is organized knowledge. Wisdom is organized life".
