Kant's Philosophy: 9 Keys to Understanding His Thought

Last update: 15 February, 2024

Immanuel Kant’s philosophy was one of the most influential of the 18th century. His ideology covered many areas of thought in this discipline, including epistemology, ethics, aesthetics, and politics.

However, understanding Kant may be difficult at first, especially because of his strictly philosophical language. Starting from this scenario, we want to propose nine important elements to help you understand the thinking of this intellectual.

Keys to understanding the philosophy of Immanuel Kant

Let’s start by mentioning the three capital works of Immanuel Kant in which a large part of his theory is contained. To understand his thinking, it’s essential to review these theories and present those relevant concepts. Let’s look at the keys below.

The importance of Kant’s philosophy today

Despite the centuries that separate us from this philosopher, his ideas are still valid today. On the one hand, the critical potential of his philosophy allows us to identify and recognize the limits of our reason and knowledge. Furthermore, it helps us find a middle ground between overconfidence in our rational capacity and, at the same time, not completely renouncing it.

On the other hand, Kant is credited with being the author who shaped human rights. The categorical imperative to respect the dignity of every person is also highlighted.

In this way, Kant’s philosophy represents a universal foundation of the value of dignity embodied in human rights. This, of course, without disregarding his philosophical anthropology that recognizes the human being as a finite and imperfect being.

Finally, Kant’s influence on later discipline was very significant. It had a resurgence in the 20th century in philosophers such as Martin Heidegger, Hannah Arendt, José Ortega y Gasset, Jüger Habermas, Karl-Otto Apel, and Theodor Adorno.
