Sartre aside, that three word phrase strikes me as having an unusually large quantity of the letter ‘e’. Let’s do the math. Studies show ‘e’ is the most frequently occurring letter in the English language at a rate slightly over 12% (almost 1 out of every 8 letters). But in Sartre’s statement ‘e’ appears as 9 of the 24 total letters. That’s 37.5% (or 3/8 if you like) – three times the average.
In mathematics, the numerical constant e is an irrational number. “Irrational Man: A Study In Existential Philosophy” is a well known book by William Barrett which helped introduce existentialism to the English speaking world. Thank you Wikipedia.
Bringing Sartre back into the discussion we see that ‘e’ has established its existence in a major way. But what about essence?
