SARTRE'S "EXISTENCE PRECEDES ESSENCE"

Sartre's "existence precedes essence" was perhaps a good battle cry against much deluded "idealism", but it is, in my opinion, bad metaphysics, or rather, impossible metaphysics. There can be no existence not characterized by some form, no 'this' devoid of 'such' as Plato would say; unless it be that bare notion of bare 'being' that means nothing and is nothing.
