not reason alone

I SHOULD LIKE BALLS infinitely better', said Caroline Bingley, 'if they were carried on in a different manner... It would surely be much more rational if conversation instead of dancing made the order of the day.' 'Much more rational, I dare say,' replied her brother, 'but it would not be near so much like a Ball.' We are told that the lady was silenced: yet it could be maintained that Jane Austen has not allowed Bingley to put forward the full strength of his position. He ought to have replied with a distinguo. In one sense conversation is more rational for conversation may exercise the reason alone, dancing does not. But there is nothing irrational in exercising other powers than our reason. On certain occasions and for certain purposes the real irrationality is with those who will not do so. The man who would try to break a horse or write a poem or beget a child by pure syllogizing would be an irrational man; though at the same time syllogizing is itself a more rational activity than the activities demanded by these achievements. It is rational not to reason, or not to limit oneself to reason, in the wrong place; and the more rational a man is the better he knows this.
