But while materialism claims as its own the consequences of the revolutionary work of chemistry, biology lays the firm foundation for a new and higher development of religious conceptions. Biology discovers and proves the existence of that spiritual body which humanity has surmised since prehistoric times. It is to this extraordinarily important fact that we desired to call attention. We have endeavored to draw its consequences only as regards the cell-generations which successively rise and die in the human body as in human society. Now when it can be shown that these dying generations are eternal and imperishable parts of man’s own nature, the conception of death and resurrection we have here advanced must be the only possible one. The hitherto common ideas regarding the translation of man to another world have upon closer study been found as naïve as they are unnatural, because any such direct transposition of man’s entity is impossible and unthinkable. But however simple and scientifically natural the theory here proposed, it could not have appeared at a much earlier date. It requires not only the results of modern cytology but also the widening of the idea of immortality which natural science suggests and overwhelmingly proves. It presupposes also the law of evolution we have endeavored to make clear, namely, that beings endowed with common wants and existing in similar surroundings and conditions cannot develop, except by the upbuilding of an organism, and thus entering as organic members in an individual of higher order than themselves. From these premises we might have deduced our theory of death and resurrection and yet the whole process would still have seemed mysterious and inexplicable but for the work of our great predecessor, _Christofer Jacob Boström_, that Plato of the North, so often misunderstood by his contemporaries, or at least more known on account of certain possible deficiencies in his system than because of its imperishable merits.
