Johann Heinrich Pestalozzi quotes
Each of our moral, mental, and bodily powers must have its development based upon its own nature, and not based upon artificial and outside influences. Faith must be developed by exercises in believing and cannot be developed from the knowledge and understanding, only, of what is to be believed; thought must grow from thinking, for it cannot come simply from the knowledge and understanding of what is to be thought, or the laws of thought; love must be developed by loving, for it does not arise merely from a knowledge and understanding of what love is and of what ought to be loved; art, also, can only be cultivated through doing artistic work and acquiring skill, for unending discussion of art and skill will not develop them. Such a return to the true method of Nature in the method of the development of our powers necessitates the subordination of education to the knowledge of the various laws which govern those powers.
Johann Heinrich Pestalozzi
