“What marks [sloth] is that it holds anxiety at bay by total absorption in an activity that raises no questions beyond itself … Sin is present not merely in the ambition that remakes the world to suit its own plans, but in the sensuality that loses itself in immediate possibilities, in the sloth that absorbs itself in petty concerns and excuses its mediocre performance, and even in the disciplined pursuit of excellences that have been carefully defined by someone else…. “Those who find their work meaningless and who lack significant personal relationships will find much encouragement in a consumer-oriented society to devote themselves to new forms of gadgetry and to establish a firm decorative control over their limited personal environment. These evasions of freedom, along with the forms of indulgence more usually associated with ‘sensuality’, must be seen as genuine forms of sin …
We must also identify a form of institutional sin that elicits sensuality or sloth from persons by demanding commitments that preclude responsible attention to the range of choices and responsibilities that they ought to be attending to for themselves. The ‘up or out’, ‘publish or perish’ career trajectories imposed by businesses, law firms, and academic institutions provide familiar examples of this sort of pressure … Those who yield to these pressures are often pictured as ambitious, ‘fast-track’ achievers whose chief temptation would seem to be to emulate the pride of their seniors and superiors. In fact, however, their achievements are often expressions of sensuality and sloth. The rising executive or scholar abandons the difficult balancing of obligations that marks a life of freedom constrained by human finitude, and substitutes a single set of goals defined by outside authorities … The over-achiever stills anxiety in precisely the way that Niebuhr describes the sensual evasion, ‘by finding a god in a person or process outside the self’.”
