Groothius on television and truth decay

Douglas Groothuis has posted a long excerpt about television from his book Truth Decay. It's strong stuff:

Television is an unreality appliance that dominates our mentality. We then take this unreality mentality and impose it on the rest of the real world. That is, we (mis)understand the world in terms of the mentality inherent to the form of communication that is television.

The excerpt is long (4400 words), but hard-hitting and highly engaging. Doug explains how television leads to truth decay and points out the relationship of images to idolatry. He also suggests ways to overcome the truth-decaying effects of television.
