Heidegger, however, has written that those two philosophers say the same thing. Remember that being means appearing, emerging and enduring. For Parmenides, true being is whatever is changeless behind the appearance of change. In their differing ways, both philosophers struggled to rescue eternal being from the flux of appearance and change. Both, heroically, tried to stamp becoming with the seal of being, which is the intellectual way of abolishing death.
Philosophers try it in a different way, by thinking immortal thoughts.
