In our days, Doubt is thorough. So thorough, that it soon ceases to be doubt, and the mind passes quickly from its dim twilight to a rayless blank. Mr. Herbert Spencer puts the case of Theology as follows (First Principles p. 43): "Criticising the essential conceptions involved in the different orders of beliefs, we find no one of them to be logically defensible. Passing over the consideration of credibility, and confining ourselves to that of conceivability, we see that Atheism, Pantheism, and Theism, when rigorously analysed, severally prove to be absolutely unthinkable." These three conceptions the writer does in fact analyse after his own fashion,--briefly first, pp. 30-36,--and further on argues the whole question _in extenso_. The result, of course, is that all three "beliefs" must finally be abandoned. What then becomes of the Absolute ground, or First Cause of all things? Spencer is too clear-sighted not to acknowledge that there must in reason be a First, and an Absolute. "M. Herbert Spencer," says Ravaisson,[107] "en proclamant la grande maxime que nous ne connaissons rien que de relatif, a fait cependant une réserve importante. L'idée même du relatif, remarque-t-il, ne saurait se comprendre sans celle à laquelle elle est opposée. Et nous concevons, en effet, au delà de toutes les relations de phénomènes, l'absolu: c'est ce quelque chose qui est placé au delà de toute science, et qui est l'objet de la religion; quelque chose seulement de mystérieux, d'obscur, sur quoi on ne peut avoir, selon M. Spencer, aucune lumière." The last negative clause is amply justified on p. 113 of "First Principles." "By continually seeking to know, and being continually thrown back with a deepened conviction of the impossibility of knowing, we may keep alive the consciousness that it is alike our highest wisdom and our highest duty to regard that through which all things exist as The Unknowable." And this closing word becomes with Spencer, the constant name of a Power, the consciousness, of which is "manifested to us through all phenomena."[108]
