"Labors [are] valuable, not because work is good, but because leisure is good." - Bertrand Russell, In Praise of Idleness
Russell's intuition is that our praise of toil as a virtue is vestigial of a feudal mentality and ought to be abandoned in favor of a more civilized ethic. This is his argument: a) Idleness is more pleasurable than work. b) technology and philosophy are such now that hard work is less and less necessary for survival. c) therefore, we ought to reorganize our society so that we work less and play more.
Of course, his argument falls flat for me because of his a priori commitment to hedonism. Unfortunately, if the chief end of man is merely to enjoy himself forever, then the system will always lean toward those with power, thus perpetuating the unsavory proportion of the few lords over the many workers. (Not to mention that I reject the hedonistic notion that all pleasure is qualitatively neutral and the only concern is to maximize its quantity and equity.) His intuition may be right, but his worldview is powerless to provide a sufficient argument to get him there.
If the chief end of man is to glorify God and enjoy Him forever, then toil may be a necessary means to His glorious ends. One of these ends is that we might be transformed with ever increasing glory into His royal image, having become lords of all creation who will enjoy God's Sabbath rest forever. (See the New Testament, particularly 2 Corinthians and Hebrews). I fear for those who would repeat the Babel Heresy by attempting to circumvent God's means to arrive at a cheap substitution for His ends. For now, we ought both to work and rest with equal vigor, knowing that the Day is near.
