Hi, Ian. If you read materials quoting the philosophy of  Disney and also read materials quoting the philosophy of Wittgenstein, you may develop an appreciation of which author provides a greater depth of presentation versus ease of presentation of their own philosophy.  The book "Strategies of Genius Vol I" does discuss Disney's philosophy.  And the bibliography of that book may contain one or more sources that actually quote Disney's writings on philosophy.  Books quoting Wittgenstein are available in the philosophy section of a bookstore.  The bibliography of the book "Whispering In The Wind" doesn't contain listings whose title or author sections contain the words "Disney" or "Wittgenstein". -nj
