Regarded as one of the great philosophers of his time, Immanuel Kant was known for his principle of humanity. In this principle, he expressed this famous line, “act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means, but always at the same time as an end. This German philosopher was born to a family of harness makers. His parents were Pietist, so he had his education at a Pietist school named Collegium Fridericianum. Though he showed strong reaction against his Pietism, Kant still had deep respect and admiration for his parents.
