Ontological Argument:

  1. {X} is conceived of as perfectly {Y}.

  2. To be perfectly {Y}, {X} must exist.

  3. Therefore, {X} exists.

This is also reminiscent of Descartes' cogito:

X cannot occur without Y. X occurs. Therefore, Y exists.

(X=thought; Y=a thinking thing)

Except that's actually valid logic.

For all X, X implies Y; X, therefore Y.

As opposed to For all X, Y is required of X; Y or not Y, therefore X. <-- invalid logic is invalid.
