Miguel de Unamuno on an Ethic of Doubt
I shall be told that this is an untenable position, that a foundation must be laid upon which to build our action and our words, that it is impossible to live by contradictions, that unity and clarity are essential conditions of life and thought, and that it is necessary to unify thought. And this leaves us as we were before. For it is precisely this inner contradiction that unifies my life and gives it its practical purpose.
Or rather it is the conflict itself, it is this self-same passionate uncertainty, that unifies my action and makes me live and work.
We think in order that we may live, I have said; but perhaps it is more correct to say that we think because we live, and the form of our thought corresponds with that of our life. Once more I must repeat that our ethical and philosophical doctrines in general are usually merely the justification a posteriori of our conduct, of our actions. Our doctrines are usually the means we seek in order to explain and justify to others and to ourselves our own mode of action. And this, be it observed, not merely for others but for ourselves. The man who does not really know why he acts as he does and not otherwise, feels the necessity of explaining to himself the motive of his action and so he forges a motive. What we believe to be the motives of our conduct are usually but the pretexts for it. The very same reason which one man may regard as a motive for taking care to prolong his life may be regarded by another man as a motive for shooting himself.
Nevertheless it cannot be denied that reason, ideas, have an influence upon human actions, and sometimes even determine them, by a process analogous to that of suggestion upon a hypnotized person, and this is so because of the tendency in every idea to resolve itself into action — an idea being simply an inchoate or abortive act. ...
But putting all this aside for the present, what I wish to establish is that uncertainty, doubt, perpetual wrestling with the mystery of our final destiny, mental despair, and the lack of any solid and stable dogmatic foundation may be the basis of an ethic.
He who bases or thinks that he bases his conduct — his inward or his outward conduct, his feeling or his action — upon a dogma or theoretical principle which he deems incontrovertible, runs the risk of becoming a fanatic, and moreover, the moment that this dogma is weakened or shattered, the morality based upon it gives way. If the earth that he thought firm begins to rock, he himself trembles at the earthquake, for we do not all come up to the standard of the ideal Stoic who remains undaunted among the ruins of a world shattered into atoms. Happily the stuff that is underneath a man's ideas will save him. For if a man should tell you that he does not defraud or cuckold his best friend only because he is afraid of hell, you may depend upon it that neither would he do so even if he were to cease to believe in hell, but that he would invent some other excuse instead. And this is all to the honour of the human race.
But he who believes that he is sailing, perhaps without a set course, on an unstable and sinkable raft, must not be dismayed if the raft gives way beneath his feet and threatens to sink. Such a one thinks that he acts, not because he deems his principle of action to be true, but in order to make it true, in order to prove its truth, in order to create his own spiritual world.
My conduct must be the best proof, the moral proof, of my supreme desire; and if I do not end by convincing myself, within the bounds of the ultimate and irremediable uncertainty, of the truth of what I hope for, it is because my conduct is not sufficiently pure. Virtue, therefore, is not based upon dogma, but dogma upon virtue, and it is not faith that creates martyrs but martyrs who create faith. There is no security or repose — so far as security and repose are obtainable in this life, so essentially insecure and unreposeful — save in conduct that is passionately good.
Conduct, practice, is the proof of doctrine, theory. "If any man will do His will — the will of Him that sent me," said Jesus, "he shall know of the doctrine whether it be of God or whether I speak of myself" (John vii. 17); and there is a well-known saying of Pascal: "Begin by taking holy water and you will end by becoming a believer." And pursuing a similar train of thought, Johan Jakob Moser, the pietist, was of the the opinion that no atheist or naturalist had the right to regard the Christian religion as void of truth so long as he had not put it to the proof by keeping its precepts and commandments (Ritschl, Geschichte des Pietismus, book vii., 43).
