What are the philosophical implications of the concept of thinking? What paths has thought traversed throughout the history of philosophy? Does thinking rest on a single model, or does it consist of multiple and varied models? What obstacles does the self-encounter when attempting to describe itself? Do we need to reflect on our personal experiences, viewing them as interwoven with the ethical and historical experiences to which we bear witness? How is the self-formed, and what is the relationship of this formation to ethics on one hand and the concept of responsibility on the other? Doesn’t the ethical component encourage the self to engage in self-criticism? Is morality not a fundamental factor in determining the effectiveness of the self and the possibility of hope? What are the main manifestations of the crisis of thinking?
