How poor, listless and unenergetic would all our performances be, but for this sentiment! It is in vain that I should talk to myself or others, of the necessity of human actions, of the connection between cause and effect, that all industry, study and mental discipline will turn to account, and this with infinitely more security on the principle of necessity, than on the opposite doctrine, every thing I did would be without a soul. I should still say, Whatever I may do, whether it be right or wrong, I cannot help it; wherefore then should I trouble the master-spirit within me? It is either the calm feeling of self-approbation, or the more animated swell of the soul, the quick beatings of the pulse, the enlargement of the heart, the glory sparkling in the eye, and the blood flushing into the cheek, that sustains me in all my labours. This turns the man into what we conceive of a God, arms him with prowess, gives him a more than human courage, and inspires him with a resolution and perseverance that nothing can subdue. In the same manner the love or hatred, affection or alienation, we entertain for our fellow-men, is mainly referable for its foundation to the "delusive sense of liberty." "We approve of a sharp knife rather than a blunt one, because its capacity is greater. We approve of its being employed in carving food, rather than in maiming men or other animals, because that application of its capacity is preferable. But all approbation or preference is relative to utility or general good. A knife is as capable as a man, of being employed in purposes of utility; and the one is no more free than the other as to its employment. The mode in which a knife is made subservient to these purposes, is by material impulse. The mode in which a man is made subservient, is by inducement and persuasion. But both are equally the affair of necessity(28)." These are the sentiments dictated to us by the doctrine of the necessity of human actions. (28) Political Justice, Book IV, Chap. VIII.
