The history of a human mind during its progressive stages of earthly experience has never as yet, I believe, been attempted. Faithfully compiled, from verified data, it would be a treasure of wisdom to all mankind, replete with light to the metaphysical and ethical inquirer. Comparative philosophy deduced from an observation of man during all circumstances and stages of his existence is a thing yet unthought of among us.

Unless those ties which connect it with others are formed, the wants of the soul become morbid and all its fresh and primal affections become dim and perverted.... Few can be happy shut out of the nursery of the soul.

Thus the baby book grew: The influence of children I regard as important to my own improvement and happiness. It is also necessary to the prosecution of my studies.
