A dictionary of Marshall McLuhan’s quotations

I must repeat once again that the chiasmus pattern is really a play of metaphors (tetrad), that the intensification of any human process, artifact, or creation will have four simultaneous consequences: it will enhance something, it will cause something to become obsolescent, bring something back, and pushed to the limit flip into an opposite effect.
