THE first two books of Aristotle's Physics do not deal with problems in what we today call physics: Aristotle's own titles for them were probably ,Qoncirjujjg_prindpks' and 'Concerning nature' (Ross,pp. 1-6), andhe^ntesjsaphilosopher, not as a scientist. Nevertheless, Phys. II, at least, seems to be addressed to the sdentifi^jtudjntjof_nature_(the phusikos: 194*16, bio, i98a2a), and both books may, perhaps, most aptly be classified as philosophy of science. This seems to be roughly how Aristotle himself conceived them, though his demarcation of fields and methods of inquiry is tentative, and may appear a little strange and academic to the modern reader
