„First, It is evident that when the Mind perceives any Idea, not immediately and of it self, it must be by the means of some other Idea. Thus, for Instance, the Passions which are in the Mind of another, are of themselves, to me invisible. I may nevertheless perceive them by Sight, tho‘ not immediately yet, by means of the Colours they produce in the Countenance. We do often see Shame or Fear in the Looks of a Man, by perceiving the Changes of his Countenance to Red or Pale.“ (no. IX) #Berkeley #idea
