The chief of our concerns is that of ourselves, yet how often have we not been told by the inner voice, that to pursue our own interests at the expense of others would be to do wrong! So we imagine that we are sometimes obeying the impulse of nature, but all the while we are resisting it. In listening to the voice of our senses, we turn a deaf ear to the dictates of our heart.

Jean-Jacques Rousseau (1712 – 1778)
