If we could obtain a distinct and full history of all that hath passed in the mind of a child from the beginning of life and sensation till it grows up to the use of reason, how its infant faculties began to work, and how they brought forth and ripened all the various notions, opin-ions, and sentiments, which we find in ourselves when we come to be capable of reflection, this would be a trea-sure of natural history which would probably give more light into the human faculties, than all the systems of philosophers about them from the beginning of the world.
Thomas Reid
