The Person as the Subject and Object of Action

We must, then, be clear right from the start that every subject also exists as an object, an objective ‘something’ or ‘somebody.(…)

Because a human being — a person — possesses free will, he is his own master. (…)No one else can want for me. No one can substitute his act of will for mine.I am, and I must be, independent in my actions. All human relationships are posited on this fact. All true conceptions about education and culture begin from and return to this point. A person must not be merely the means to an end for another person. Anyone who treats a person as the means to an end does violence to the very essence of the other.
Nobody can use a person as a means towards an end, no human being, nor yet God the Creator.
If God intends to direct man towards certain goals, he allows them to begin to know those goals, so that he may make them his own and strive towards them independently.
