Unjustified claim by Erasistrateans that their founder
had associations with the Peripatetic (Aristotelian)
school. The characteristic physiological tenets of that
school (which were all anticipated by Hippocrates) in no
way agree with those of Erasistratus, save that both
recognize the purposefulness of Nature; in practice,
however, Erasistratus assumed numerous exceptions to
this principle. Difficulty of understanding why he
rejected the biological principle of attraction in
favour of anatomical factors.
