If you are merely a sceptic, you must sooner or later ask yourself the question, "Why should ANYTHING go right; even observation and deduction? Why should not good logic be as misleading as bad logic? They are both movements in the brain of a bewildered ape?" The young sceptic says, "I have a right to think for myself." But the old sceptic, the complete sceptic, says, "I have no right to think for myself. I have no right to think at all."
There is a thought that stops thought. That is the only thought that ought to be stopped. That is the ultimate evil against which all religious authority was aimed. It only appears at the end of decadent ages like our own: and already Mr. H. G. Wells has raised its ruinous banner; he has written a delicate piece of scepticism called "Doubts of the Instrument." In this he questions the brain itself, and endeavours to remove all reality from all his own assertions, past, present, and to come.
