From 1805 to 1807 he was commander-in-chief of the Swedish forces in Pomerania, where he displayed great ability and retarded the conquest of the duchy as long as it was humanly possible.
Here then we have the basis of a view in which there are not two media to be considered, but one medium, homogeneous in essence and differentiated as regards its parts only by the presence of nuclei of intrinsic strain or motion - in which the physical activities of matter are identified with those arising from the atmospheres of modified aether which thus belong to its atoms. As regards laws of general physical interactions, the atom is fully represented by the constitution of this atmosphere, and its nucleus may be left out of our discussions; but in the problems of biology great tracts of invariable correlations have to be dealt with, which seem hopelessly more complex than any known or humanly possible physical scheme.
The value and interest of the Perceval romances stand very high, not alone for their intrinsic merit, though that is considerable - Chretien's Perceval, though not his best poem, is a favourable specimen of his work, and von Eschenbach's Parzival, though less elegant in style, is by far the most humanly interesting, and at the same time, most deeply spiritual, of the Grail romances - but also for the interest of the subject matter.
Again, it assumes an ideal of truth which turns out to be humanly unattainable and incompatible with the existence of error, an d an ideal of science which no human science can be conceived as attaining.
In every way humanly possible.
