Ockham’s razor cartoon (or Occam’s razor cartoon). Occam’s razor is the name given to the principle that from among competing hypotheses or ideas the one that gives the simplest and least complex explanation or that makes the fewest new assumptions is more likely to be correct.
Occam’s razor gets its name from William of Ockham, an English Franciscan friar and philosopher. He didn’t actually originate the maxim that the simpler an explanation was the more likely it was to be correct, but he used the concept frequently so the maxim became associated with him.
The joke in the cartoon is that Occam finds all of the razors in a shop too complicated, as he thinks that a simpler one will do the job better.
