Late last century, a certain fruit-based computer company ran an advertising campaign with the slogan “Think Different.” The TV and posters featured portraits of many creative geniuses, but one group was conspicuously missing: Logicians!

To correct this, ALS produced parody posters featuring some of the founders of mathematical logic, David Hilbert and Gottlob Frege. Going beyond mere “thinking”, the poster exhort us to “Unify Different.” and “Infer Different.”

The Posters:

  • ALS Prolog, Unify Different - Hilbert

  • ALS Prolog, Infer Different - Frege
