Abstract
In this paper, the author attempts to make explicit certain of the key variables that underlie
the wide variety of positions which have been offered in answer to the question posed by the
title of the paper. Several positions are reviewed briefly, ranging from Bertrand Russell’s to
Jasper’s to Milton Meyer’s to Thoreau’s. These are then considered as a group in terms of
possible systems of values which traditionally have formed the basis for condemnations or
defenses of political and social silence, of marginal commitment, or of individual nonparticipation
or complicity. The author does not hope to settle the issue, but rather to
increase our sensitivity to it, and to its complexity.
