To the former of these Sects we may justly annumerate all such, who conceived the soul of man to be only a certain harmony, not of Musical sounds, but a contemperation of parts, humours, and qualities; and consequently, that as of Musical Harmony, nothing can remain after the sounds are vanished, so of the soul nothing can remain, after death hath once destroyed that harmonious Contemperation of parts, humours, and qualities, from whence it did result.
And this purely was the opinion of not only those ancienter Greeks, Dicaearchus, Aristoxenus, Andraeas, and Asclepiades, all which are thereof strongly accused by Plato (in Phaed.) and Aristotle (Lib. I. de Anima. Cap. 5.) but also our Master Galen, who was positive an plain in his definition of the soul, to be a certain Temperament of Elementary Qualities.
