The Philebus appears to be one of the later writings of Plato, in which the style has begun to alter, and the dramatic and poetical element has become subordinate to the speculative and philosophical. In the development of abstract thought great advances have been made on the Protagoras or the Phaedrus, and even on the Republic. But there is a corresponding diminution of artistic skill, a want of character in the persons, a laboured march in the dialogue, and a degree of confusion and incompleteness in the general design.
