dr. Farkas László: A sejtelmélet és a dialektikus materializmus. II. rész

Haeckel admits all through his Jife the positive, rational features of Vir~ chow's cell-pathology. At the same time he comes up against Virchow's celldogma, as he very aptly cells it, and severly criticizes it from the view-point of natural-historical materialism and instinctive dialectics. Engels affirms that the results of the investigations of living matter are apt to loosen and, in a certain sense, to make relative the supposedly rigid borderline between the phenomena and the objects. This statement of Engels' is also based upon the cell-theory of Schleiden and Schwann, as well as upon Haeckel's theory about „Plastidula". One of E. Haeckel's greatest merits is his criticism of the hypotheses of heredity, which appear under different shapes but are, all of them, fundamentally teleological ; Weismann's germ-plasma-hypothcsis is one of them. Haeckel's criticism gave us a weapon which we can succesfully handle even today against upholders of the reactionary racial theory and the skilfully disguised modern trends of Wcismannism and Morganism -in defence of" classical Darwinism and its lawful heir, the theories of Mitchourine.
