“ The mind is shocked at the cruelty of the one, or is induced to lament the blindness of the other; and as nothing is less permanent in life than those external relations, which are more frequently produced by accident than wisdom, and which are called weakness or power, riches or poverty, all human institutions seem at first glance to be founded merely on banks of shifting sand. ”
 Jean-Jacques Rousseau, Discourse on the Origin of Inequality Among Men (1755). copy citation

“The very study of the original man, of his real wants, and the fundamental principles of his duty, is besides the only proper method we can adopt to obviate all the difficulties which the origin of moral inequality presents, on the true foundations of the body politic, on the reciprocal rights of its members, and on many other similar topics equally important and obscure. If we look at human society with a calm and disinterested eye, it seems, at first, to show us only the violence of the powerful and the oppression of the weak. The mind is shocked at the cruelty of the one, or is induced to lament the blindness of the other; and as nothing is less permanent in life than those external relations, which are more frequently produced by accident than wisdom, and which are called weakness or power, riches or poverty, all human institutions seem at first glance to be founded merely on banks of shifting sand. It is only by taking a closer look, and removing the dust and sand that surround the edifice, that we perceive the immovable basis on which it is raised, and learn to respect its foundations. Now, without a serious study of man, his natural faculties and their successive development, we shall never be able to make these necessary distinctions, or to separate, in the actual constitution of things, that which is the effect of the divine will, from the innovations attempted by human art.” source
