The scope of the Philosophical Thoughts, and the attitude of Diderot's mind when they were written, may be shown in a few brief passages. The opening words point to the significance of the new time in one direction, and they are the key-note to Diderot's whole character. "People are for ever declaiming against the passions; they set down to them all the pains that man endures, and quite forget that they are also the source of all his pleasures. It is regarded as an affront to reason if one dares to say a word in favour of its rivals. Yet it is only passions, and strong passions, that can raise the soul to great things. Sober passions produce only the commonplace. Deadened passions degrade men of extraordinary quality. Constraint annihilates the greatness and energy of nature. See that tree; 'tis to the luxury of its branches that you owe the freshness and the wide-spreading breadth of its shade, which you may enjoy till winter comes to despoil it of its leafy tresses. An end to all excellence in poetry, in painting, in music, as soon as superstition has once wrought upon human temperament the effect of old age! It is the very climax of madness to propose to oneself the ruin of the passions. A fine design truly in your pietist, to torment himself like a convict in order to desire nothing, love nothing, feel nothing; and he would end by becoming a true monster, if he were to succeed!"[34] Many years afterwards he wrote in the same sense to Madame Voland. "I have ever been the apologist of strong passions; they alone move me. Whether they inspire me with admiration or horror, I feel vehemently. If atrocious deeds that dishonour our nature are due to them, it is by them also that we are borne to the marvellous endeavour that elevates it. The man of mediocre passion lives and dies like the brute." And so forth, until the writer is carried to the perplexing position that "if we were bound to choose between Racine, a bad husband, a bad father, a false friend, and a sublime poet, and Racine, good father, good husband, good friend, and dull worthy man, I hold to the first. Of Racine, the bad man, what remains? Nothing. Of Racine, the man of genius? The work is eternal."[35] Without attempting to solve this problem in casuistry, we recognise Diderot's mood, and the hatred with which it would be sure to inspire him for the starved and mutilated passions of the Christian type. The humility, chastity, obedience, indolent solitude, which had for centuries been glorified by the Church, were monstrous to this vehement and energetic spirit. The church had placed heroism in effacement. Diderot, borne to the other extreme, left out even discipline. To turn from his maxims on the foundation of conduct, to his maxims on opinion. As we have said, his attitude is that of the sceptic:—
What has never been put in question, has not been proved. What people have not examined without prepossessions, they have not examined thoroughly. Scepticism is the touchstone. (§ 31.)
Incredulity is sometimes the vice of a fool, and credulity the defect of a man of intelligence. The latter sees far into the immensity of the Possible; the former scarcely sees anything possible beyond the Actual. Perhaps this is what produces the timidity of the one, and the temerity of the other.
A demi-scepticism is the mark of a feeble understanding. It reveals a pusillanimous reasoner, who suffers himself to be alarmed by consequences; a superstitious creature, who thinks he is honouring God by the fetters which he imposes on his reason; a kind of unbeliever who is afraid of unmasking himself to himself. For if truth has nothing to lose by examination, as is the demi-sceptic's conviction, what does he think in the bottom of his heart of those privileged notions which he fears to sound, and which are placed in one of the recesses of his brain, as in a sanctuary to which he dares not draw nigh? (§ 34.)
Scepticism does not suit everybody. It supposes profound and impartial examination. He who doubts because he does not know the grounds of credibility, is no better than an ignoramus. The true sceptic has counted and weighed the reasons. But it is no light matter to weigh arguments. Who of us knows their value with any nicety? Every mind has its own telescope. An objection that disappears in your eyes, is a colossus in mine: you find an argument trivial that to me is overwhelming. … If then it is so difficult to weigh reasons, and if there are no questions which have not two sides, and nearly always in equal measure, how come we to decide with such rapidity? (§ 24.)
When the pious cry out against scepticism, it seems to me that they do not understand their own interest, or else that they are inconsistent. If it is certain that a true faith to be embraced, and a false faith to be abandoned, need only to be thoroughly known, then surely it must be highly desirable that universal doubt should spread over the surface of the earth, and that all nations should consent to have the truth of their religions examined. Our missionaries would find a good half of their work done for them. (§ 36.)
One thing to be remembered is that Diderot, like Vauvenargues, Voltaire, Condorcet, always had Pascal in his mind when dealing with apologetics. They all recognised in him a thinker with a love of truth, as distinguished from the mere priest, Catholic, Anglican, Brahman, or another. "Pascal," says Diderot, "was upright, but he was timid and inclined to credulity. An elegant writer and a profound reasoner, he would doubtless have enlightened the world, if Providence had not abandoned him to people who sacrificed his talents to their own antipathies. How much to be regretted, that he did not leave to the theologians of his time the task of settling their own differences; that he did not give himself up to the search for truth, without reserve and without the fear of offending God by using all the intelligence that God had given him. How much to be regretted that he took for masters men who were not worthy to be his disciples, and was foolish enough to think Arnauld, De Sacy, and Nicole, better men than himself." (§ 14.) The Philosophic Thoughts are designed for an answer in form to the more famous Thoughts of this champion of popular theology. The first of the following extracts, for instance, recalls a memorable illustration of Pascal's sublime pessimism. A few passages will illustrate sufficiently the line of argument which led the foremost men at the opening of the philosophic revolution to reject the pretensions of Christianity:—
What voices! what cries! what groans! Who is it that has shut up in dungeons all these piteous souls? What crimes have the poor wretches committed? Who condemns them to such torments? The God whom they have offended. Who then is this God? A God full of goodness. But would a God full of goodness take delight in bathing himself in tears? If criminals had to calm the furies of a tyrant, what would they do more? … There are people of whom we ought not to say that they fear God, but that they are horribly afraid of him. … Judging from the picture they paint of the Supreme Being, from his wrath, from the rigour of his vengeance, from certain comparisons expressive of the ratio between those whom he leaves to perish and those to whom he deigns to stretch out a hand, the most upright soul would be tempted to wish that such a being did not exist. (§§ 7–9.)
You present to an unbeliever a volume of writings of which you claim to show him the divinity. But, before going into your proofs, he will be sure to put some questions about your collection. Has it always been the same? Why is it less ample now than it was some centuries ago? By what right have they banished this work or that, which another sect reveres, and preserved this or that, which the other has repudiated? … You only answer all these difficulties by the avowal that the first foundations of the faith are purely human; that the choice between the manuscripts, the restoration of passages, finally the collection, has been made according to rules of criticism. Well, I do not refuse to concede to the divinity of the sacred books a degree of faith proportioned to the certainty of these rules. (§ 59.)
People agree that it is of the last importance to employ none but solid arguments for the defence of a creed. Yet they would gladly persecute those who attempt to cry down the bad arguments. What then, is it not enough to be a Christian? Am I also to be one upon wrong grounds? (§57.)
The less probability a fact has, the more does the testimony of history lose its weight. I should have no difficulty in believing a single honest man who should tell me that the king had just won a complete victory over the allies. But if all Paris were to assure me that a dead man had come to life again, I should not believe a word of it. That a historian should impose upon us, or that a whole people should be mistaken—there is no miracle in that. (§46.)
What is God? A question that we put to children, and that philosophers have much trouble to answer. We know the age at which a child ought to learn to read, to sing, to dance, to begin Latin or geometry. It is only in religion that you
