Abstract

The First Dialogue of Three Dialogues covers a lot of ground. It introduces the two characters of the Dialogues, lays down the issue to be discussed, and, by means of the conversation, wrings from Hylas two important concessions. Hylas, who is apparently accustomed to sleeping in, opens the dialogue by revealing that he is up early due to a problem on his mind arising from a late night discussion. Philonous responds with a flowery and enthusiastic account of the beauties of nature to be enjoyed by the early riser. Philonous gets from Hylas the willing admission that nothing is perceived immediately except the proper objects of the senses. George Berkeley leads into the discussion of primary and secondary qualities from a last ditch attempt by Hylas to resurrect his argument about sound with respect to color. He proposes that color is nothing more than the motion of light particles.
