The author presents the method of philosophizing practiced by Bogusław Wolniewicz. He subsequently discusses the sources of his philosophizing, the objectives he has set for himself, his rationalism as well as his method of making philosophy scientifically sound. The author also mentions Wolniewicz’s use of history of philosophy and substantive philosophy, his method of working with students in classes, and finally his work on texts. In many places, the author expands this presentation by adding elements of his own meta-philosophy.
