A number of aspects of the cosmology of Anaximenes of Miletus have not yet been convincingly explained, but we can assume that a starting point was the notion of a universe stretching only between a flat earth and heaven. This gave the cosmology its “meteorological” character: heavenly bodies were viewed as ignited evaporations of moisture. They were thought of as moving only above the earth’s surface, and their rising and setting were explained as an optical illusion. Similar approaches appear not (...) only in the Greek epic tradition but even in the writings of Xenophanes. It can therefore be assumed that Anaximenes’s conception is representative of contemporary Ionian explanations of cosmological events. (shrink)

Aristotle is oftentimes viewed through a strictly philosophical lens as heir to Plato and has having introduced logical rigor where an emphasis on the theory of Forms formerly prevailed. It must be appreciated that Aristotle was the son of a physician, and that his inculcation of the thought of other Greek philosophers addressing health and the natural elements led to an extremely broad set of biologically- and medically-related writings. As this article proposes, Aristotle deepened the fourfold theory of the elements (...) with anatomic and physiologic observations. In books like History of Animals, Parts of Animals, and the lost Anatomai, he actively dissected organisms and recorded his findings. The corpus of medically-related literature Aristotle developed had a direct influence on subsequent Greek thinkers, including Galen, and on Medieval Islamic and modern Western practitioners such as William Harvey. Aristotle's ideas continue to influence modern medical thinkers in Europe and America through both his interpretation by European philosophers gaining the attention of medical humanists, and his writings' enduring impact on medical researchers balancing scientific with more personalistic approaches to medicine.

Few things can be more confusing, or confused, than the ancient reports about Empedocles' astronomy. Attempts in the modern literature at resolving the difficulties invariably either add to the confusion, or end by urging the need to ‘acknowledge the insufficiency of our data and suspend judgment’. In fact, as we will see, it is possible not only to reconstruct Empedocles' own ideas but also to retrace the history of their subsequent misunderstanding.
