Post Hoc Ergo Propter Hoc - Pattern

Pattern

The form of the post hoc fallacy can be expressed as follows:

  • A occurred, then B occurred.
  • Therefore, A caused B.

When B is undesirable, this pattern is often extended in reverse: Avoiding A will prevent B.

Famous quotes containing the word pattern:

    It is a very true and expressive phrase, “He looked daggers at me,” for the first pattern and prototype of all daggers must have been a glance of the eye.... It is wonderful how we get about the streets without being wounded by these delicate and glancing weapons, a man can so nimbly whip out his rapier, or without being noticed carry it unsheathed. Yet it is rare that one gets seriously looked at.
    Henry David Thoreau (1817–1862)

    Swift while the woof is whole,
    turn now my spirit, swift,
    and tear the pattern there,
    the flowers so deftly wrought,
    the border of sea-blue,
    the sea-blue coast of home.
    Hilda Doolittle (1886–1961)

    It was her stern necessity: all things
    Are of one pattern made; bird, beast, and flower,
    Deceive us, seeming to be many things,
    And are but one. Beheld far off, they differ
    As God and devil; bring them to the mind,
    They dull its edge with their monotony.
    Ralph Waldo Emerson (1803–1882)
