From Freedom, Morality, and New Year Revolutions at One Cosmos:
You will notice that when you pick up most any "new age" type book -- in fact, unfortunately, many conventional religious books as well -- the language conveniently goes "wobbly" just at that critical juncture when you most need it. These frauds use language in such a way that they make you feel as if the fault is within you, not them. Philosophers and academics pull the same thing all the time. But if you truly understand something, then it shouldn't be difficult to find the words to convey that understanding to another, at least assuming adequate communication skills, along with good will in the reader. (I might add that where the new agers use fuzzy language to conceal their ignorance, the conventionally religious often fall back on overly rigid and saturated formulas to cover over their lack of understanding.)
It's a good observation, and I have noticed that too. And mea culpa, Gagdad Bob: I have done the same sometimes.
