The article looks at critical thinking in philosophical counselling and the concepts upon which it is based. In conceptions that place critical thinking as the basis of philosophical counselling, an important role is played by the Socratic approach to philosophising. The Socratic method in thinking allocates a fundamental role to conversation, and thus to intersubjectivity, and is therefore an alternative to individual ways of thinking. Conversation as philosophical reflection corresponds to the Socratic intersubjective understanding of truth. The author adopts the (...) view of German philosopher H. Schnädelbach who distinguishes between dialogic and doctrinal approaches. The dialogic approach is found in the Socratic-Platonic tradition, while the doctrinal approach is found in Aristotelean approaches. Doctrinal philosophising is premised in the ideal of intersubjectivity which can be achieved by anyone. Philosophical thought as reflection is always implicitly dialogic at the very least. The article considers definitions of critical thinking and provides examples of critical thinking based philosophical counselling from the thinking of Tim LeBon and Elliot D. Cohen, which link both philosophical and psychological approaches. In conclusion it is critical of an excessive focus on rationality in counselling. (shrink)
