Our only book should be the living individual; all the rest taken together form only the necessary means for reading it.
2. The Passage from Analysis to Synthesis.—Assuming that we have learned how to gather anthropological data with a rigorously exact technique, and that we possess a theoretic knowledge and tables of comparative data: all this together does not suffice to qualify us as interpreters of nature. The marvellous reading of this amazing book demands on our part still other forms of preparation. In gathering the separate data, it may be said that we have learned how to spell, but not yet how to read and interpret the sense. The reading must be accomplished with broad, sweeping glances, and must enable us to penetrate in thought into the very synthesis of life. And it is the simple truth that life manifests itself through the living individual, and in no other way. But through these means it reveals certain general properties, certain laws that will guide us in grouping the living individuals according to their common properties; it is necessary to know them, in order to interpret individual differences dependent upon race, age, and sex, and upon variations due to the effort of adaptation to environment, or to pathological or degenerative causes. That is to say, certain general principles exist, which serve to make us interpreters of the meaning, when we read in the book of life.
This is the loftiest part of our work, carrying us above and beyond the individual, and bringing us in contact with the very fountain-heads of life, almost as though it were granted us to materialise the unknowable. In this way we may rise from the arid and fatiguing gathering of analytical data, toward conceptions of noble grandeur, toward a positive philosophy of life; and unveil certain secrets of existence, that will teach us the moral norms of life.
Because, unquestionably, we are immoral, when we disobey the laws of life; for the triumphant rule of life throughout the universe is what constitutes our conception of beauty and goodness and truth—in short, of divinity.
The technical method of proceeding toward synthesis, we may find well defined in biology: the data gathered by measurement can be grouped according to the statistical method, be represented graphically and calculated by the application of mathematics to biology: to-day, indeed, biometry and biostatistics tend to assume so vast a development as to give promise of forming independent sciences.
The method in biology, considered as a whole, may be compared to the microscope and telescope, which are instruments, and yet enable us to rise above and beyond our own natural powers and come into contact with the two extremes of infinity; the infinitely little and the infinitely large.
Objections and Defences.—One of the objections made to pedagogical anthropology is that it has not yet a completely defined content, on which to base an organic system of instruction and reliable general rules.
It is the method alone that enables us to be eloquent in defence of pedagogic anthropology, against such an accusation. For the accusation itself is the embodiment of a conception of a method differing widely from our own: it is the accusation made by speculative science, which, resting on the basis of a content, refuses to acknowledge a science that is still lacking and incomplete in its content, because it is unable to conceive that a science may be essentially summed up in its method, which makes it a means of revelation.
How could we conceive of the content of pedagogic anthropology otherwise than as something to be derived by the experimental method from the observation of school-children? And where could we conceive of a possible laboratory for such a science, if not in the school itself? The content will be determined little by little, by the application of the anthropological study to school-children in the school, and never in any other manner.
Now, if it were necessary to await the completion of a content before proceeding to any practical application, where could we hope to get this content from—especially since we look for no help either from speculative philosophy or divine revelation?
