In appealing to the young on the aspiration after improvement, one cannot say 'Consult your aptitudes--follow your bias.' This Is the sole appeal-injunctive to which all natures can respond. But in this half-natured, half-trained, doubtfully-conditioned state of society, though the generous would be incited to noble deeds, the sordid would lay their vulture claws on the world, and the unprincipled victimise their fellows. You have, therefore, to say, 'Man, do what thou listest, provided it be compatible with the welfare of thy fellow men.' Men are not well-natured, and we have thus to guard individuality, and qualify the appeal, and so we miss the soil of great enterprise. Great is the disadvantage. For the fulcrum which is to raise men is without their natures--remote in the wide world. Man should begin with himself. He loves Truth--it is the first impulse of his nature. He loves Justice--the bandit on the throne, as well as the bandit in the forest, respects justice in some form or other. Man loves Cheerfulness--it is the attribute of innocence and courage. He loves Fraternity--it knits society together in brotherhood. These are standards. His codes of life and judgment arise from these aspirations. That which accords with these principles is _reasonable_. Whatever develops these principles in conduct is _moral_. These sentiments are to be confirmed by his own observations. His experience in connection with these rules is the right with which he may examine religions, creeds, books, systems, opinions. The right understanding of physical and moral facts greatly depends upon intellectual character--and there enters largely into the recondite and ultimate inquiries of intelligent men another class of facts, called mental facts. There is no chance of identifying these without the power of self-analysis, which is one reason why metaphysic ability belongs to so few, and why questions involving metaphysical considerations are such profound enigmas to the majority of the people. The illiterate in these things are easily led or misled by words. They who will not bow before a throne fall prostrate before a sound.
