Mental masturbation 

the act of engaging in intelligent and interesting conversation purely for the enjoyment of your own greatness and individuality. Subjects range from obscure lp's to cultural movements in preindustrial societies. Either delivered through grand monlogues or subtle conversation orientation, it links large words and random references resulting in nothing acually being communicated.

<\paraphrasing>

Dr. Dawkins, commenting on Boswell's question, and critiquing the attitude: "If you want to mess about with that sort of mental masturbation, thats fine, but, ... but the science of reality is what gets you through the day, ... and makes things work!"
