Inconsistent Triad

An inconsistent triad consists of three propositions of which at most two can be true. For example:

  1. Alice loves me.
  2. If Alice loves me, she would have sent flowers.
  3. Alice hasn't sent flowers.

If one finds oneself believing all three propositions of an inconsistent triad, then (to be rational) one must give up or modify at least one of those beliefs. Maybe Alice doesn't love me, or maybe she wouldn't send flowers to me if she did, or maybe she actually has sent flowers.

Famous quotes containing the word inconsistent:

    For by superior energies; more strict
    Affiance in each other; faith more firm
    In their unhallowed principles, the bad
    Have fairly earned a victory o’er the weak,
    The vacillating, inconsistent good.
    William Wordsworth (1770–1850)
