# Quote — Jean Jacques Rousseau, Emile; or On Education

> In the following books I have still to speak of the training of a sort of sixth sense, called common-sense, not so much because it is common to all men, but because it results from the well-regulated use of the other five, and teaches the nature of things by the sum-total of their external aspects. So this sixth sense has no special organ, it has its seat in the brain, and its sensations which are purely internal are called percepts or ideas.
