One of the greatest of all philosophy books is René Descartes’s Meditations. Written in Holland in 1641, almost all undergraduates exposed to philosophy read the Meditations. It is an epochal work, a brilliant affirmation of rationality, but, in my opinion, it is another book written in Holland that has its thesis confirmed at every turn. Johan Huizinga’s 1938 Homo Ludens proposes that civilizations are built from play, not reason.
