When George Grant delivered Philosophy in the Mass Age over the CBC radio network early in 1958, it was an immediate hit. He criticized the Western notion of progress and affirmed the role of philosophy in teaching and assisting people in understanding.

The controversial introduction to the 1966 edition appears as an appendix.
