8. Another life must be described, if at all, in forms of thought and not of sense. To draw pictures of heaven and hell, whether in the language of Scripture or any other, adds nothing to our real knowledge, but may perhaps disguise our ignorance. The truest conception which we can form of a future life is a state of progress or education--a progress from evil to good, from ignorance to knowledge. To this we are led by the analogy of the present life, in which we see different races and nations of men, and different men and women of the same nation, in various states or stages of cultivation; some more and some less developed, and all of them capable of improvement under favourable circumstances. There are punishments too of children when they are growing up inflicted by their parents, of elder offenders which are imposed by the law of the land, of all men at all times of life, which are attached by the laws of nature to the performance of certain actions. All these punishments are really educational; that is to say, they are not intended to retaliate on the offender, but to teach him a lesson. Also there is an element of chance in them, which is another name for our ignorance of the laws of nature. There is evil too inseparable from good (compare Lysis); not always punished here, as good is not always rewarded. It is capable of being indefinitely diminished; and as knowledge increases, the element of chance may more and more disappear. 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;
