From his writings, Ibn Bajjah has been shown to take a liking to Plato's contribution to philosophy. Ibn Bajjah, in particular, takes from Plato's idea of the necessary connection between man and city with a bit of a twist. Plato 's idea was to model the perfect city after the human soul. On the other hand, Avempace wanted to use the perfect city as a model for the human soul. Avempace imagines the perfect city as a place that is free of any beliefs or opinions that are in opposition of the truth and where true science reigns supreme. Any man or idea that contradicts these true beliefs are defined as "weeds." Weeds are only to be found in imperfect cities.
