One of the many challenges facing those taking up Aristotle’s zoological writings, or more generally even such works as his “Physics,” is that of understanding the very different scope of his explorations and explanations from what such would be were they to have been undertaken by a modern writer. Indeed, even the very word “physics” (from the Greek φύσις) itself had a very different meaning to Aristotle and his contemporaries than how we use the word today.
