Although there have doubtless been long lapses of time during which the human race has seemed to go backward, it is believed that the trend of humanity is now and ever has been upward. If, as is believed, human events move in cycles, if the civilizations which have risen in the past represent a spiral, each of these civilizations reaching a higher stage of development than its predecessor, then it may be inferred that the era which is now dawning will surpass in grandeur anything which the world has ever witnessed. If, as many persons believe, a stage of development has been reached in which human beings are to be endowed with a sixth sense, if the intuitive faculties which are closely allied to the constructive element and which mark a still greater distinction between man and the animal are to come into play it may be assumed that the mental and spiritual faculties will reach a stage of development scarcely dreamed of in our own time. Humanity will have come into its own, the animal in man will have been left behind. The co-ordination of science and history not only illumines the past and explains the present, but the inevitable results of the natural sequence of events point unerringly to the conditions which must prevail in the future. The philosophy of history proves to the earnest seeker after truth that the door of the future is not wholly closed.
