Dickens satirizes Utilitarianism in Hard Times

Now, what I want is, Facts. Teach these boys and girls nothing but Facts. Facts alone are wanted in life. Plant nothing else, and root out everything else. You can only form the minds of reasoning animals upon Facts: nothing else will ever be of any service to them. This is the principle on which I bring up my own children, and this is the principle on which I bring up these children. Stick to Facts, sir!' (Chap. I.)

'Why, my dear Louisa,' said Mr. Gradgrind, completely recovered by this time, 'I would advise you (since you ask me) to consider this question, as you have been accustomed to consider every other question, simply as one of tangible Fact. The ignorant and the giddy may embarrass such subjects with irrelevant fancies, and other absurdities that have no existence, properly viewed - really no existence - but it is no compliment to you to say, that you know better. Now, what are the Facts of this case? You are, we will say in round numbers, twenty years of age; Mr. Bounderby is, we will say in round numbers, fifty. There is some disparity in your respective years, but in your means and positions there is none; on the contrary, there is a great suitability. Then the question arises, Is this one disparity sufficient to operate as a bar to such a marriage? In considering this question, it is not unimportant to take into account the statistics of marriage, so far as they have yet been obtained, in England and Wales. I find, on reference to the figures, that a large proportion of these marriages are contracted between parties of very unequal ages, and that the elder of these contracting parties is, in rather more than three-fourths of these instances, the bridegroom. It is remarkable as showing the wide prevalence of this law, that among the natives of the British possessions in India, also in a considerable part of China, and among the Calmucks of Tartary, the best means of computation yet furnished us by travellers, yield similar results. The disparity I have mentioned, therefore, almost ceases to be disparity, and (virtually) all but disappears.' (Chap. XV.)
