These are not accidental tags. They point toward defining characteristics and tendencies of the philosophical style. The strongest possible evidence is demanded for claims of the timelessness or universality of any concept or idea. It is hardly possible to pick up a newspaper or listen to NPR today without realizing that cosmology and cosmogony are one again topics of everyday discussion. Physicists are practicing philosophy, in a reversal of the pattern of specialization of disciplines that has dominated the academic world since the Enlightenment.
Philosophy is once again front page news.
Plato devoted substantial attention to reviewing and criticizing the views of his predecessors, and Aristotle made the history of philosophy the starting point of many philosophical discussions. In this activity they were inventing and defining philosophical historiography. For the history of ideas consists, primarily, in reconstructing the logical structure of thought of our predecesors and, secondarily, in criticizing that structured thought. The history of philosophy sets its own, high ethical standards. Such criticism is, in the view of your instructor, bad logic, bad history, and bad philosophy.
