Prometheus devotes, on an average, ten hours a day to labor, seven to rest, and seven to pleasure. In order to gather from his toil the most useful fruit, Prometheus notes the time and trouble that each object of his consumption costs him. Only experience can teach him this, and this experience lasts throughout his life. While laboring and producing, then, Prometheus is subject to an infinitude of disappointments. But, as a final result, the more he labors, the greater is his well-being and the more idealized his luxury; the further he extends his conquests over Nature, the more strongly he fortifies within him the principle of life and intelligence in the exercise of which he alone finds happiness; till finally, the early education of the Laborer completed and order introduced into his occupations, to labor, with him, is no longer to suffer,--it is to live, to enjoy. But the attractiveness of labor does not nullify the rule, since, on the contrary, it is the fruit of it; and those who, under the pretext that labor should be attractive, reason to the denial of justice and to communism, resemble children who, after having gathered some flowers in the garden, should arrange a flower-bed on the staircase. In society, then, justice is simply the proportionality of values; its guarantee and sanction is the responsibility of the producer. Prometheus knows that such a product costs an hour's labor, such another a day's, a week's, a year's; he knows at the same time that all these products, arranged according to their cost, form the progression of his wealth. First, then, he will assure his existence by providing himself with the least costly, and consequently most necessary, things; then, as fast as his position becomes secure, he will look forward to articles of luxury, proceeding always, if he is wise, according to the natural position of each article in the scale of prices. Sometimes Prometheus will make a mistake in his calculations, or else, carried away by passion, he will sacrifice an immediate good to a premature enjoyment, and, after having toiled and moiled, he will starve. Thus, the law carries with it its own sanction; its violation is inevitably accompanied by the immediate punishment of the transgressor.
