The fundamental triad of I. Kant is the triad to which, as I. Kant asserts, any other triad is reduced, for example, the French "Liberté, Égalité, Fraternité". Is the fundamental triad capable of serving as a "guiding star" for all of humanity and for each person, regardless of their education or religious self-identification? Is it possible for contemplation of this triad to lead a person to the path of truth and keep their consciousness and will on this path? This can only be verified by popularizing the fundamental triad.
