Every one sees that love is a desire, and we know also that non-lovers desire the beautiful and good. Now in what way is the lover to be distinguished from the non-lover? Let us note that in every one of us there are two guiding and rul-ing principles which lead us whither they will; one is the natural desire of pleasure, the other is an acquired opinion which aspires after the best; and these two are sometimes in harmony and then again at war, and sometimes the one, sometimes the other conquers.
This interesting to think about because it gets your brain thinking about what makes the differences here and is it based off of opinion?
