  • adj. Of or relating to a form of argument in which a series of incomplete syllogisms is so arranged that the predicate of each premise forms the subject of the next until the subject of the first is joined with the predicate of the last in the conclusion. For example, if one argues that a given number of grains of sand does not make a heap and that an additional grain does not either, then to conclude that no additional amount of sand will make a heap is to construct a sorites argument.
  • n. A sorites argument.

  • n. An abridged form of stating of syllogisms in a series of propositions so arranged that the predicate of each one that precedes forms the subject of each one that follows, and the conclusion unites the subject of the first proposition with the predicate of the last proposition.

  • Sorites arguments of the paradoxical form are to be distinguished from multi-premise syllogisms (polysyllogisms) which are sometimes also referred to as sorites arguments.

    Sorites Paradox

  • Your sorites doesn't negate my concept of "a reading experience"; it just demands that I don't pretend it's identical to the author's.

    Whether true or not

  • Neither "my experience" nor the "100% intellectually valid" queer reading are meant to be identical to the author's intention, and so your sorites is still attacking a point I'm not defending.

    Whether true or not

  • Since I have failed to clarify my argument against your concept of “reading experience,” let me reduce it to a sorites:

    Whether true or not

  • Actual ordinary mid-sized objects have vague boundaries, so the sorites argument may be used to show that we have no coherent non-trivial criterion of identity for them.

    Possible Objects

  • The evidence nonetheless suggests that Zeno anticipated reasoning related to that of the sorites paradox, apparently invented more than a century later.

  • Similarly, it is possible to construct sorites series for the application of even more abstract legal standards such as the United States constitutional prohibition on cruel and unusual punishment, or the right to due process -- evaluative tests with special legal meanings that can only be understood in the context of a whole legal system (and by reference to their elaboration and development in a common law system of precedent).

  • That is, those considerations do not provide a way of distinguishing between one tire in the sorites series and the next.
