If the actual sensation of positive pain was in itself so little to be feared, that of pleasure was still less to be desired. Naturally the sensation of pleasure was much less pungent than that of pain. If, therefore, this last could take so very little from the happiness of a well-disposed mind, the other could add scarce any thing to it. When the body was free from pain and the mind from fear and anxiety, the superadded sensation of bodily pleasure could be of very little importance; and though it might diversify, could not be properly be said to increase the happiness of this situation. In ease of body, therefore, and in security or tranquillity of mind, consisted, according to Epicurus, the most perfect state of human nature, the most complete happiness which man was capable of enjoying. To obtain this great end of natural desire was the sole object of all the virtues, which, according to him, were not desirable upon their own account, but upon account of their tendency to bring about this situation. Prudence, for example, though according to this philosophy, the source and principle of all the virtues, was not desirable upon its own account. That careful and laborious and circumspect state of mind, ever watchful and ever attentive to the most distant consequences of every action, could not be a thing pleasant or agreeable for its own sake, but upon account of its tendency to procure the greatest goods and to keep off the greatest evils. To abstain from pleasure too, to curb and restrain our natural passions for enjoyment, which was the office of temperance, could never be desirable for its own sake. The whole value of this virtue arose from its utility, from its enabling us to postpone the present enjoyment for the sake of a greater to come, or to avoid a greater pain that might ensue from it. Temperance, in short, was nothing but prudence with regard to pleasure. To support labour, to endure pain, to be exposed to danger or to death, the situations which fortitude would often lead us into, were surely still less the objects of natural desire. They were chosen only to avoid greater evils. We submitted to labour, in order to avoid the greater shame and pain of poverty, and we exposed ourselves to danger and to death in defence of our liberty and property, the means and instruments of pleasure and happiness; or in defence of our country, in the safety of which our own was necessarily comprehended. Fortitude enabled us to do all this chearfully, as the best which, in our present situation, could possibly be done, and was in reality no more than prudence, good judgment, and presence of mind in properly appreciating pain, labour, and danger, always choosing the less in order to avoid the greater.
