It is easy to say that all things are both good and beautiful at once and that these qualities exist in nature simultaneously. It is not possible, however, to enjoy what is "good" about a thing and what is "beautiful" about it at the same moment. A pear is good: to know its goodness I must eat it. A pear may be beautiful: to know its beauty I must not eat it, I must resolutely refuse its goodness, I must let it alone. Goodness yields itself to use; the reason I am justified in calling a pear "good" is that when I do use it, when I eat it, it proves to be good for me. But in the process of eating it, of using it up, I am of course destroying all of the properties that enabled me to call it "beautiful."
