This collection contains four of Ethel Kitch Yeaton's notebooks from courses she took with Edward Scribner Ames and James Hayden Tufts, professors of philosophy at The University of Chicago. Two of her notebooks, one entitled "Psychology 44" concerning the psychology of religion, and another entitled "Abnormal Psychology," were probably taken in lecture from Ames. A third notebook, "Philosophy Seminar," contains notes from a lecture Tufts delivered on Kant's ethical theory and "Critique of Pure Reason." Lecture notes from another class given by Tufts are found in the fourth notebook, "Philosophy 12." Some of the notebooks also contain various loose notes.
