There is no "theory" or "guess-work" about it. It becomes, step by step, a matter of conscious, intelligent, individual experience. We know it just as we know that fire will burn or that we are here now, living, breathing, and acting. If I thrust my finger into a flame, all the philosophers and metaphysicians of the world could not "argue" me out of the experience of the fact of "burn" and "pain"; nor could theologians succeed any better by quotations from Scripture! Man is so constituted that the _facts_ of _experience_ are stubborn things; and the more open to reason the individual the more convincing the facts of experience. Ignorance, superstition, and fear recede in the presence of these Lights of man's intelligence, as do dogma and despotism, that seek to enslave the human soul. Theologians tell us that it is exceeding dangerous to take all this responsibility upon ourselves, thus appealing to ignorance, superstition, and fear. I would answer: I refuse to take the responsibility of _disregarding_ or _disobeying_ the Law which the Divine and Universal Intelligence has placed at the _very foundation_ of man's being; and I am so _un_orthodox as to imagine and believe that God knew what he was about, even better than the theologians, or the "Infallible" Italian who misinterprets God, Nature, and Man. To-day, as I write, "God's Vicegerent" is instigating and promoting a "Holy War" in Priest-ridden Spain, over the temporal power of the Vatican, angered to the point of murder over the "posting of notices of places of public worship," other than Catholic. They would rather turn the world into one "City of the Dead," than yield _one point_ of Freedom, Enlightenment, or Self-government to man. And men still call this _Religion_, and cast aside the crucifix for the sword, the gun and the firebrand. The _Inferno_ has never yet been portrayed or even outlined. Its name is Priestcraft and Intolerance under the name of "Religion." And is this a "Study in Psychology"? Yea, verily! Scientific Psychology is the only thing that goes to the very bottom of it, and defines and classifies every element, every fact in human experience. Man cannot build a _home_ on a piece of ground where a slaughter-house disputes every square yard of ground with the tombstones of a graveyard. Clericalism is ever the one or the other, and frequently both; denying to man the right to build a _home_ for himself anywhere, except by its permission and according to its plans and specifications, fixing the rent and the revenues for all future time. The Premier of Spain to-day is disputing this prerogative of Rome, and the graveyard has been thrown open. The pity, the marvel of it all is, that the people generally do not seem to care, and call any statement of facts "sensational" or "panicky." I am told by some very good people that these references to Popery seem irrelevant, and by others, that they mar the symmetry of my essay.
