عقولُ البشر مرايا لبعضها البعض، لا لأنها تعكس انفعالات بعضها فحسب، بل لأن تلك الأشعة من الأهواء والمشاعر والآراء كثيراً ما ترتدّ وتتلاشى بدرجاتٍ لا يُدرَك تدرّجها.

“The minds of men are mirrors to one another, not only because they reflect each other's emotions, but also because those rays of passions, sentiments and opinions may be often reverberated, and may decay away by insensible degrees.”David Hume — A Treatise on Human Nature: Being an Attempt to Introduce the Experimental Method of Reasoning Into Moral Subjects; and Dialogues Concerning Natural Religion (1874)
