quent to the Platonic-Aristotelian differentiation might apply the 

 name philosophy to his teaching. For Thales, his work was, how- 

 ever, neither science nor philosophy, simply because the distinction 

 had not, in his time, been made. For this reason, it is logically 

 incorrect to speak of the relation of science and philosophy before 

 the time of Plato. But history subsequent to his writings is, as it 

 were, a great stage upon which the two characters, science and 

 philosophy, play important and yet extremely varied roles. A 

 delineation of the part played by each and of the interrelations of the 

 two must now be entered upon.
