Freedom and Moral Autonomy: Metaphysical Foundations

La Libertad: Freedom and Moral Autonomy

Freedom as a Presupposition of Morality

La Libertad. The ideas of metaphysics are presented theoretically or scientifically, but when they are assumed as conditions of the possibility of morality they have a different significance. Freedom is a presupposition of morality: we cannot speak of morality unless we begin by accepting that human beings can be free.

Phenomenal and Noumenal Aspects of the Human

A human being can be considered as a natural, sensitive (phenomenal) subject to the laws of nature, but may also be considered as a free subject of rationality and free will that allows one to rise above or be thought of apart from the laws of nature (noumena). If we take the human as merely natural and believe that the human will is free, then we must ask whether their actions are determined only by empirical grounds, like animals, or whether they can be otherwise.

Inclinations, Psychology, and the Moral Dimension

Our sensuous inclinations all have a selfish and subjective character. The study of this dimension corresponds to human psychology: it studies what a person does, not what they ought to do. From the standpoint of what people do, one can understand the influence of inclination and determinism. Determinism is the determination of action by external factors, whether physical or emotional; this is incompatible with true freedom.

Freedom, Rationality, and Voluntariness

Another way to consider human beings—both as a species and as individuals—is as beings whose rationality and conscience allow them to escape or stand apart from the mere laws of nature. Only then can we consider a person as free and voluntary. Freedom is independence with respect to natural law.

Can Freedom Exist under Determinism?

If a person were merely an object of nature determined by external forces, like animals or inert objects, then there would be no room for moral law. Can that constitute freedom? Freedom is understood in two senses: in a negative sense, as independence from the necessities and contingencies of empirical causes; and in a positive sense, as the capacity of self-determination determined by the will itself.

Autonomy Versus Heteronomy

This positive sense is called autonomy: the individual's ability to give oneself voluntary and conscious standards for action and to act according to them. The contrary is heteronomy: the individual's tendency to internalize rules imposed by others and act upon them. We behave heteronomously when we follow rules imposed by others or when we act in accordance with demands imposed by our inclinations and desires.

Practical Reason and Moral Action

A person acts freely and autonomously when carrying out an action because that is what their reason dictates, even against their own desires and sensible inclinations. Freedom is the supreme condition of morality. It cannot be scientifically proven, but it must be assumed at a practical level. We cannot talk about morality without the prior assumption that humans can act freely.

Responsibility and A Priori Reason

Freedom is the only idea whose responsibility is known a priori by reason because it is the condition of the moral law. In other words, practical reason presupposes freedom as a necessary condition for moral responsibility.

Key Concepts

• Phenomenal: the natural, sensuous aspect of human beings subject to empirical laws.
• Noumenal: the rational aspect that enables the idea of freedom beyond empirical determination.
• Autonomy: self-legislation and moral self-determination.
• Heteronomy: acting according to rules or inclinations imposed from outside.
• Determinism: action determined by external physical or emotional causes.

Freedom, then, functions as a metaphysical and practical presupposition for moral discourse: while it may elude empirical demonstration, it remains essential for the concepts of duty, responsibility, and moral law.
