Cudworth, Ralph (1617-1688)

A Treatise Concerning Eternal and Immutable Morality

London

Printed for James and John Knapton

1731

"Wherefore that we may the better understand how far the Passion of Sense reaches, and where the Activity of the Mind begins, we will compare these three Things together: First, a Mirror, Looking-glass or Crystal Globe; Secondly, a Living Eye, that is, a Seeing or Perceptive Mirror or Looking-glass; Thirdly, a Mind or Intellect Superadded to this Living Eye or Seeing Mirror."

2. But that which imposes upon Mens Judgements here, so as to make them think, that these are all Passive Impressions made upon the Soul by the Objects of Sense, is nothing else but this; because the Notions both of those Relative Ideas, and also of those other other Immaterial things, (as Vertue, Wisdom, the Soul, God) are most Commonly Excited and awakened occasionally from the Appulse of Outward Objects knocking at the Doors of our Senses. And these Men not distinguishing betwixt the Outward Occasion or Invitation of those Cogitations, and the immediate Active or Productive Cause of them, impute them therefore all alike, as well these intelligible, as the other Sensible Ideas, or Phantasms, to the Efficiency or Activity of the, outward Objects upon us. Wherefore that we may the better understand how far the Passion of Sense reaches, and where the Activity of the Mind begins, we will compare these three Things together: First, a Mirror, Looking-glass or Crystal Globe; Secondly, a Living Eye, that is, a Seeing or Perceptive Mirror or Looking-glass; Thirdly, a Mind or Intellect Superadded to this Living Eye or Seeing Mirror.
