The following is from Dr. Nicholas Murray Butler, president of the New York College for the Training of Teachers, 1886.
"If the term manual training is used in antithesis to mental training, it is wrongly understood. Manual training, as I use the term is mental training. It is included in the psychologically determined course of study because it reaches important mental faculties which no other studies reach. It is also a most valuable and important stimulus to the receptive faculty of observation. The child can neither draw accurately, nor construct correctly unless he observes acutely."
