Anaximander on Nature

Anaximander was a younger contemporary and a fellow-citizen of Thales; we need not accept the conventional statement that they were teacher and pupil, in order to believe that the younger man knew and was stimulated by his senior’s excogitations. Anaximander became ‘the first Greek whom we know to have produced a written account Concerning Nature’ (Themistius, 12 A 7). ¹
