Abstract

There are good reasons for determinism — the option for pure freedom of will proves to be a non-tenable position. However, this collides with the everyday experience of autonomy. The following argument will attempt to show that determinism and autonomy are compatible. A first consideration going back to MacKay makes clear that I myself cannot foresee in principle my own determination; hence fatalism has lost its grounds. From the perspective of physical determination, I show that quantum-physical indetermination is not at all in a position to explain autonomy, while from the perspective of systems theory physical determination and autonomy is well-compatible. The possibility of knowledge denotes a further increase of such autonomy. From this perspective, acting is something like designing-oneself or choice-of-oneself. Consciousness of not being fixed in principle now becomes a determining condition of my acting, which appears to be determined by autonomy. This explains the ineradicable conviction that freedom of will is essential for human beings. I conclude that the autonomy of acting is greater the more that rational self-determination takes the place of stupid arbitrariness.
