That every effect has an adequate cause. That all things made had a Maker. That there must have been a First Cause. That all things change. That nothing can be annihilated. That wickedness should be punished. That goodness should be rewarded. That all happiness depends on the state of mind. That there is a permeating spirit moving on all the events about mankind. That man must eat to live. That when man has done his best, yet his success still depends on Providence--often called Good Fortune or Good Luck. That prayer can influence external conditions. That light is not darkness. That love is not hate. That up is not down. That the future is not the past. That all men must leave the body. That mankind is sinful. That somewhere justice must be done to clear up the inequalities of this life. That men essentially evil would not be at home or welcomed in a heaven occupied only by the good. That worshiping an ideal of perfect righteousness makes the worshiper like the ideal, as a perfect model makes a more perfect statue. That some things have more intrinsic value than others. That the highest satisfaction of soul is in the communion with God. That the soul is indestructible and must live forever. These axioms are unchangeably true, and all doubts or attempts to "prove" them bring only confusion and partial insanity. To doubt generally that we see or feel or smell or think is to undermine all knowledge and to make life a crazy jumble. Some things we do know; it is suicidal to doubt them. These are mankind's chief good. They constitute the world's greatest treasure, which is "everyday common sense." If common sense, unadulterated, be given any man he will worship God. The keenest scientist cannot safely leap off that one ship.
