I consider that to be less of a specific logical pattern than a breed of syllogism, one which is only true from a particular philosophical standpoint. That might be Berkeleian idealism, perhaps?

It's a perfectly valid view in more vigorous metaphysical structures, of course, and you find its equally blinkworthy converse in starey-eyed evangelical atheism. Well, I find I blink more often when people stare at me, at any rate.
