To this we again reply: Every cause must produce an effect, because until it does produce an effect, it is not a cause. Every effect must in its turn become a cause. Therefore, in the nature of things, there cannot be a last cause, for the reason that a so-called last cause would necessarily produce an effect, and that effect must of necessity become a cause. The converse of these propositions must be true. Every effect must have had a cause, and every cause must have been an effect. Therefore, there could have been no first cause. A first cause is just as impossible as a last effect Beyond the universe there is nothing, and within the universe the supernatural does not and cannot exist The moment these great truths are understood and admitted, a belief in general or special providence becomes impossible. From that instant men will cease their vain efforts to please an imaginary being, and will give their time and attention to the affairs of this world. They will abandon the idea of attaining any object by prayer and supplication. The element of uncertainty will, in a great measure, be removed from the domain of the future, and man, gathering courage from a succession of victories over the obstructions of nature, will attain a serene grandeur unknown to the disciples of any superstition. The plans of mankind will no longer be interfered with by the finger of a supposed omnipotence, and no one will believe that nations or individuals are protected or destroyed by any deity whatever. Science, freed from the chains of pious custom and evangelical prejudice, will, within her sphere, be supreme. The mind will investigate without reverence, and publish its conclusions without fear. Agassiz will no longer hesitate to declare the Mosaic cosmogony utterly inconsistent with the demonstrated truths of geology, and will cease pretending any reverence for the Jewish scriptures. The moment science succeeds in rendering the church powerless for evil, the real thinkers will be outspoken. The little flags of truce carried by timid philosophers will disappear, and the cowardly parley will give place to victory--lasting and universal. If we admit that some infinite being has controlled the destinies of persons and peoples, history becomes a most cruel and bloody farce. Age after age, the strong have trampled upon the weak; the crafty and heartless have ensnared and enslaved the simple and innocent, and nowhere, in all the annals of mankind, has any god succored the oppressed. Man should cease to expect aid from on high. By this time he should know that heaven has no ear to hear, and no hand to help. The present is the necessary child of all the past. There has been no chance, and there can be no interference.
