In that case, will is based on something external and is determined by an object, which is expected to give satisfaction. That kind of will is based on self-love. While turning this will into action, we place ourselves higher than others caring about our own satisfaction. However, what people seek from the experiences with these objects, their expectations are different from each other. Thus, such principles, which presuppose an object, cannot be universally binding. If morality is based on such principle, it would differ among people and wills of people would contradict. Thus, knowledge-oriented experience cannot be a basis for our feeling of obligation. According to Kant, to gain knowledge we have to start with an object and knowledge cannot occur without experience. However, as long as we make our decisions in the realm of experiences, we cannot raise our maxim to a moral law. The only thing holds the maxim to pure will, a universal law regardless of natural laws or what inclination we have is the human reason. In that case, our will is a pure will independent of any empirical condition and is conditioned by the mere form of law. .
Feeling of obligation cannot be deduced from a basic principle such as Plato's idea of Good or Descartes" cogito because such ideas are not knowable and representable and they are above human reason and autonomy. According to Kant anything independent from experience, unconditional cannot be known and represented. Knowledge always starts with an object, then our human mind provides conditions, which are time and space, to make this object perceivable. Knowledge occurs when we connect this perception to a concept by our judgments. Therefore, we cannot take an idea that is unconditional, beyond experience and try to represent it out of space and time. Such principles like the idea of Good and cogito refer to something unconditional, independent from experience, out of space and time.
