You don't think Frankl tackles head-on the meaning of existence? I mean, he's the father of logotherapy, which, as Wiki describes it, is "a type of Existential Analysis that focuses on a 'will to meaning' as opposed to Adler's Nietzschian doctrine of 'will to power' or Freud's of 'will to pleasure;'."

Can't get much more specific about dealing with existential crises than that, right?

Hmmm... yes, you're right, my mistake.
