Every human being is a world in miniature. It has its own centre of observation, its own way of forming concepts and of arriving at conclusions, its own degree of sensibility, its own life's work to do, and its own destiny to reach. All these features may be encompassed by general conditions, governed by general laws, and subject to unforeseen influences and incidents, but within the sphere of their own activity, they constitute that great principle which we call individuality.
