The article deals with the oldest criticism of Anaximander’s monism, for which we have evidence, found in John Philoponus’ commentary on the first book of Aristotle’s Physics . Philoponus’ argumentation is analytically examined and explained, its premises brought to light and its conclusions evaluated. It is shown how his inquiry, although anticipating modern discussions about the classification of Anaximander’s doctrine in terms of ‘monism’ and ‘pluralism’, differs from the contemporary approach to the problem when it comes to both results and (...) methodology.

The article deals with the Greek idea of circular thought and especially with the question of its presence and meaning in the philosophy of Parmenides of Elea. A new interpretation of the fragment DK 28 B 5, which is crucial to this issue, is proposed. It is suggested that the circularity of thought refers to the deductive mode of the arguments in the “Aletheia” and to the proleptic character of some of the Parmenidean statements. Both fragment B 5 (to be (...) placed probably at the beginning of the deduction of the “Aletheia”) and B 8.50-51 (the end of the “Aletheia”) may be successfully interpreted on the basis of this idea. The proposed interpretation makes clear why the circularity of thought does not oppose the linearity of the reasoning and why the logical character of cognition does not contradict its immediacy for Parmenides.

The article deals with the question of the value of the history of philosophy for philosophical research. In the first part, it proposes a classification of possible functions realized by references to the philosophical tradition in a philosophical treatise. The proposed typology is meant as a practical tool for identifying and comparing the usage of the past in philosophical texts of any historical period. The second part of the paper illustrates how the classification can be employed by applying it to (...) determine the functions of Aristotle’s discussions of the pre-Socratic doctrines in Metaphysics A.
