Abstract

The question about the object, method, and nature of Psychology in the first half of the 19th century received three proposals: the first, presented by Christian Wolff, appealed to the conciliation between the Psychologia Rationalis and the Psychologia Empirica based on the process of Experimentalphysik and in the Principle of Sufficient Reason; the second, proposed a shift towards Physiology this proposal was responsible for establishing the Psychology as an independent Science; the third offers an existential approach to mental phenomena. We argue that the project of Søren Kierkegaard presents a Psychology Experimenterende as a response to Psychologia Empirica and the Experimentelle Psychologie.
