The Phaedrus is closely connected with the Symposium, and may be regarded either as introducing or following it. The two Dialogues together contain the whole philosophy of Plato on the nature of love, which in the Republic and in the later writings of Plato is only introduced playfully or as a figure of speech. But in the Phaedrus and Symposium love and philosophy join hands, and one is an aspect of the other. The spiritual and emotional part is elevated into the ideal, to which in the Symposium mankind are described as looking forward, and which in the Phaedrus, as well as in the Phaedo, they are seeking to recover from a former state of existence.

There, lying down amidst pleasant sounds and scents, they will read the speech of Lysias. The country is a novelty to Socrates, who never goes out of the town; and hence he is full of admiration for the beauties of nature, which he seems to be drinking in for the first time…
