Chapter 24

Generation is the initial participation¹, mediated² by warm substance, in the nutritive soul, and life is the maintenance of this participation. Youth is the period of the growth of the primary organ of refrigeration, old age of its decay, while the intervening time is the prime of life.

A violent death or dissolution consists in the extinction³ or exhaustion⁴ of the vital heat (for either of these may cause dissolution), while natural death is the exhaustion of the heat owing to lapse⁵ of time, and occurring at the end of life. In plants this is to wither⁶, in animals to die. Death, in old age, is the exhaustion due to inability on the part of the organ, owing to old age, to produce refrigeration. This then is our account of generation and life and death, and the reason for their occurrence in animals.
