Until all nations and peoples become united by the bonds of the Holy Spirit in this real fraternity, until national and international prejudices are effaced in the reality of this spiritual brotherhood, true progress, prosperity and lasting happiness will not be attained by man. This is the century of new and universal nationhood. Sciences have advanced, industries have progressed, politics have been reformed, liberty has been proclaimed, justice is awakening. This is the century of motion, divine stimulus and accomplishment; the century of human solidarity and altruistic service; the century of universal peace and the reality of the divine Kingdom. DIVINE LOVE Every subject presented to a thoughtful audience must be supported by rational proofs and logical arguments. Proofs are of four kinds: first, through sense-perception; second, through the reasoning faculty; third, from traditional or scriptural authority; fourth, through the medium of inspiration. That is to say, there are four criterions or standards of judgment by which the human mind reaches its conclusions. We will first consider the criterion of the senses. This is a standard still held to by the materialistic philosophers of the world. They believe that whatever is perceptible to the senses is a verity, a certainty and without doubt existent. For example, they say, “Here is a lamp which you see, and because it is perceptible to the sense of sight you cannot doubt its existence. There is a tree; your sense of vision assures you of its reality which is beyond question. This is a man; you see that he is a man; therefore he exists.” In a word, everything confirmed by the senses is assumed to be as undoubted and unquestioned as the product of five multiplied by five; it cannot be twenty-six nor less than twenty-five. Consequently the materialistic philosophers consider the criterion of the senses to be first and foremost.
