Book 1 — CHAPTER I. Of the Principles of Pure Practical Reason. I. DEFINITION.
Thomas Kingsmill Abbott translation
BOOK1|CHAPTER1 ^paragraph 5
Practical principles are propositions which contain a general determination of the will, having under it several practical rules. They are subjective, or maxims, when the condition is regarded by the subject as valid only for his own will, but are objective, or practical laws, when the condition is recognized as objective, that is, valid for the will of every rational being.
