Abstract

In a world of change, we see species go from common to rare and yet are unable to point to any moment at which they ceased to be common. We see people grow old and yet cannot nominate any moment at which they ceased to be young. Nonetheless, transitions like these surely must occur at some point, if at all. There must be a change somewhere but no particular point can be singled out as the point of change. Where then are we to draw the line? This puzzling question lies at the heart of the ancient sorites paradox and the more general class of paradoxical arguments that now go by that name. In what follows we look at the various forms the paradox can take and some of the responses that have been pursued.

In a world of change, we see species go from common to rare and yet are unable to point to any moment at which they ceased to be common. We see people grow old and yet cannot nominate any moment at which they ceased to be young, and we see societies become unjust and yet cannot nominate any moment at which they ceased to be just. Nonetheless, transitions like these surely must occur at some point, if at all. There must be a change somewhere but no particular point can be singled out as the point of change. Where then are we to draw the line?

Notes

  1. 1.

    This chapter reproduces part of my “The Sorites Paradox” in E. Zalta (ed), The Stanford Encyclopedia of Philosophy (2005). URL: http://plato.stanford.edu.

  2. 2.

    For more on this see Barnes (1982).

  3. 3.

    Of course, if one supposes that all and only vague terms are soritical then Sorensen’s argument can be invoked without hesitation. The additional argument invoked here makes no such supposition. It is supposed that only vague terms are soritical but not that all vague terms are. For more see § 3.

  4. 4.

    See, for example, Keefe (2000: 7).
