Harriet Martineau,
Household Education
“ While the bodily powers of the infant are nourished and preserved by observing Nature, as pointed out in the last chapter, the powers of the mind are growing from day to day. When an infant has once been pleased with the glitter of the sun upon the brass warming-pan, or with the sound of a rattle, it will kick and shake its little arms, and look eager, the next time it sees the rattle and the warming-pan. And having once remembered, it will remember more every day. ”
