The intellect is an organ composed of several groups of functions, divisible into two important classes, the functions and faculties of the right hand and the functions and faculties of the left hand. The faculties of the right hand are comprehensive, creative and synthetic; the faculties of the left hand critical and analytic.
To the right hand belong Judgment, Imagination, Memory, Observation; to the left hand Comparison and Reasoning. The critical faculties distinguish, compare, classify, generalise, deduce, infer, conclude; they are the component parts of the logical reason. The righth and faculties comprehend, command, judge in their own right, grasp, hold and manipulate. The right-hand mind is the master of knowledge, the left-hand its servant.
The left hand touches only the body of knowledge, the right hand penetrates its soul. The left hand limits itself to ascertained truth, the right hand grasps that which is still elusive or unascertained. Both are essential to the completeness of the human reason. These important functions of the machine have all to be raised to their highest and finest working-power, if the education of the child is not to be imperfect and one-sided…
In education the latter are fostered by scientific and manual training, but the only quality of the right hand that this education fosters is observation. For this reason a purely scientific education tends to make thought keen and clear-sighted within certain limits, but narrow, hard and cold. Even in his own sphere the man without any training of the right hand can only progress in a settled groove; he cannot broaden the base of human culture or enlarge the bounds of science.
