Abstract
It is a question of ascertaining, at first, the difficulties that prevented Reinhold from carrying out the long-sought deduction of a free and absolute cause for freedom of will within the framework of elementary philosophy, or in the plan of the faculty of representation in general. In a second moment, I briefly analyze the author's new strategy when trying to carrying out, or at least to deepen, his foundational approach through practical philosophy. These two movements have Kantian philosophy as a background. In fact, Reinhold takes this starting point after analyzing Kant’s work and considering it problematic in some points, mainly the foundation of the effectiveness of freedom in the fact of reason.
