Kant’s famous sayings are:

1. The principle of self-discipline is the only moral principle. ——Kant's "Foundation of Moral Metaphysics"

2. Thinking without intuition is empty, and intuition without concepts is blind. ——Kant's "Critique of Pure Reason"

3. I can't make people better unless they still have kindness left in them; I can't make people smarter unless they still have some sense in them. . ——Kant's "Almanac of Wisdom"

4. One word of hope and one word is better than all the knowledge in the world. ——Kant's "Faust"

5. There are two things. The more deeply and persistently I think about them, the more lasting the admiration and awe they arouse in my soul will be. New, one is the vast and brilliant starry sky above our heads, and the other is the lofty moral law in our hearts. They confirmed to me that God is above my head and in my heart. ——Kant's "Critique of Practical Reason"

6. These orders either only take into account the results and their sufficiency, and stipulate the causality of rational beings as the working causes. Conditions, either only stipulate the will, regardless of whether it is sufficient to achieve the effect. The former will be hypothetical imperatives and contain only skilled norms; the latter, on the other hand, will be categorical and will be the only practical law.

So although maxims are principles, they are not commands. However, if the commands themselves are conditional, that is, if they do not stipulate the will absolutely as a will, but only take into account some kind of being. It is stipulated by the desired results, that is, if they are just hypothetical commands, then although they are practical norms, they are by no means practical laws. ——Kant's "Critique of Practical Reason"
