Many philosophers have set a lot of store by authenticity. In fact, perhaps the best-ever piece of light verse about a philosopher introduces it, in the exacting double-dactyl form:

Higgledy-piggledy

Herr Rektor Heidegger

Said to his students

"To Being be True!

Lest you should fall into

Inauthenticity

This I believe -

And the Führer does too!"

The verse suggests that there is something fake about Heidegger's injunctions to authenticity, and it is easy to sympathise.
