But the earth is not yet a Paradise. Theology is not yet entirely banished; the debris of the decayed beliefs still cumber our path and impede our progress. There is even now much that remains to be done. Plenty of labor to be performed. Ignorance, poverty, and crime and misery still exist and exert their evil influence in the world. The philanthropist and the reformer have still their work to do. The ignorant have yet to be instructed, the hungry have yet to be fed, the homeless have yet to be provided for. And I have come to the opinion after years of experience, that ignorance is the real cause of all the misery and suffering in the world; that that man is truly wise who sees that it is against his own interest to do a paltry act, to perform an evil deed. All actions carry with them their consequences, and you can no more escape the effects of your evil deeds than you can evade the law of gravitation, or elude the grim monster Death when the dread hour arrives. No. If you would be happy you must act virtuously--act as you would desire all others to do to promote your happiness. Say to yourselves: "if every one were to act as I am doing, would the world be benefited?" and if you come to the opinion that the world would not be improved by such conduct, depend upon it your actions are not good. Remember that once you perform a deed in Nature it is irrevocable; and if it is bad repentance is worse than useless. All actions either have an evil or a good result. Every deed leaves its indelible impress on the book of Nature, from which no leaves can be torn and nothing can be expunged. And remember, too, that the man who makes his fellow-creatures happy cannot displease a god who is good; and a god who is not good is neither deserving of admiration nor service. An infinite and all-powerful god cannot need the assistance of man; but man needs the assistance of his brothers and sisters to diffuse the glorious light of knowledge through the world; needs assistance to alleviate suffering, to remove injustice, and secure the possibility of freedom and happiness for all. Therefore I urge you to abate not your enthusiasm, but work bravely on; and when the evening of your life approaches, with wife by your side and your children playing joyously about you, with many friends to cheer and thank you--then will you know that your life's labor has not been in vain.
