Another "Cynthia you rock my world" note left in a Derrida book...

Found in "Points... Interviews 1974-1994" (Stanford university Press)

Spinoza put down

Found in a copy of the Works of Spinoza.

Schopenhauer notes

Found in a paperback copy of "On the Basis of Morality"by Schopenhauer. I can't read this handwriting; maybe it's something interesting. From Wikipedia: "Schopenhauer settled permanently in Frankfurt in 1833, where he remained for the next twenty-seven years, living alone except for a succession of pet poodles named Atman and Butz."

Copious notes?

Found in "Derrida" by Christopher Norris. Between the lines, indeed.

Come all ye shoppers...

Found in copy of "Wittgenstein's Poker: The Story of a Ten-Minute Argument Between Two Great Philosophers" by David Edmonds & John Eidinow, paperback edition.
