For we do not argue merely from the analogy of the present state of this world to another, but from the analogy of a probable future to which we are tending. The greatest changes of which we have had experience as yet are due to our increasing knowledge of history and of nature. They have been produced by a few minds appearing in three or four favoured nations, in a comparatively short period of time. May we be allowed to imagine the minds of men everywhere working together during many ages for the completion of our knowledge? May not the science of physiology transform the world? Again, the majority of mankind have really experienced some moral improvement; almost every one feels that he has tendencies to good, and is capable of becoming better. And these germs of good are often found to be developed by new circumstances, like stunted trees when transplanted to a better soil. The differences between the savage and the civilized man, or between the civilized man in old and new countries, may be indefinitely increased. The first difference is the effect of a few thousand, the second of a few hundred years. We congratulate ourselves that slavery has become industry; that law and constitutional government have superseded despotism and violence; that an ethical religion has taken the place of Fetichism. There may yet come a time when the many may be as well off as the few; when no one will be weighed down by excessive toil; when the necessity of providing for the body will not interfere with mental improvement; when the physical frame may be strengthened and developed; and the religion of all men may become a reasonable service. [Sidenote: _The immortality of the soul._] Nothing therefore, either in the present state of man or in the tendencies of the future, as far as we can entertain conjecture of them, would lead us to suppose that God governs us vindictively in this world, and therefore we have no reason to infer that he will govern us vindictively in another. The true argument from analogy is not, ‘This life is a mixed state of justice and injustice, of great waste, of sudden casualties, of disproportionate punishments, and therefore the like inconsistencies, irregularities, injustices are to be expected in another;’ but ‘This life is subject to law, and is in a state of progress, and therefore law and progress may be believed to be the governing principles of another.’ All the analogies of this world would be against unmeaning punishments inflicted a hundred or a thousand years after an offence had been committed. Suffering there might be as a part of education, but not hopeless or protracted; as there might be a retrogression of individuals or of bodies of men, yet not such as to interfere with a plan for the improvement of the whole (cp. Laws, x. 903).
