Selective Doubt, or 'Why Get Married? It's Just a Piece of Paper!'

Rene Descarte, you will remember, employed methodological doubt. He doubted everything--his sense experience, his memory, human authority--until he found something which he believed he could not doubt, namely, his own thought. Cogito, ergo sum. 'I think, therefore I am.' 'That's how I know I exist,' Descartes concluded.

Whatever you may think of Descarte's method, Theodore Dalrymple, a British physician and social critic, describes how human beings often use Descarte's doubting method selectively in order to justify their own whims and desires.

WE MAY I N Q U I R E why it is that there are now so many Descartes in the world, when in the seventeenth century there was only one. Descartes, be it remembered, who so urgently desired an indubitable first philosophical principle, was a genius: a mathematician, physicist, and philosopher who wrote in prose of such clarity, that it is still the standard by which the writing of French intellectuals is, or ought to be, judged. Have we, then, bred up a race of philosophical giants, whose passion is to examine the metaphysics of human existence? I hope I will not be accused of being an Enemy of the People when I beg leave to doubt it.

The popularity of the Cartesian method is not the consequence of a desire to remove metaphysical doubt, and find certainty, but precisely the opposite: to cast doubt on everything, and thereby increase the scope of personal license, by destroying in advance any philosophical basis for the limitation of our own appetites. The radical skeptic, nowadays at least, is in search not so much of truth, as of liberty-that is to say, of liberty conceived of the largest field imaginable for the satisfaction of his whims. He is in the realm of moral conceptions what the man who refuses to marry is in the realm of relationships: he is reluctant to foreclose on any possibilities by imposing limits on himself, even ones that are taken to be purely symbolic. I once had a patient who attempted suicide because her long-time lover refused to propose to her. I asked him the reason for his refusal, and he replied that it (marriage) was only a piece of paper and meant nothing. "If it is only a piece of paper and means nothing," I asked him, "why do you not sign it? According to you, it would change nothing, but it would give her a lot of pleasure." Suddenly, becoming a man of the deepest principle, he said that he did not want to live a charade. I could almost hear the argument that persuaded the man that he was right: that true love and real commitment are affairs of the heart, and need no sanction of the church or state to seal them.

The skepticism of radical skeptics who demand a Cartesian point from which to examine any question, at least any question that has some bearing on the way they ought to conduct themselves, varies according to subject matter. Very few are so skeptical that they doubt that the sun will rise tomorrow, even though they might have difficulty offering evidence for the heliocentric (or any other) theory of the solar system. These skeptics believe that when they turn the light switch, the light will come on, even though their grasp of the theory of electricity might not be strong. A ferocious and insatiable spirit of inquiry overtakes them, however, the moment they perceive that their interests are at stake-their interests here being their freedom, or license, to act upon their whims. Then all the resources of philosophy are available to them in a flash, and are used to undermine the moral authority of custom, law, and the wisdom of ages.
