Identity and Difference.

Identity and Difference consists of English translations and the original German versions of two little-known lectures given in 1957 by Martin Heidegger, "The Principle of Identity" and "The Onto-theo-logical Constitution of Metaphysics." Both lectures discuss the difficult problem of the nature of identity in the history of metaphysics. A helpful introduction and a list of references are also provided by the translator, Joan Stambaugh.
