Known as the father of social medicine, Rudolf Virchow owes this title to his Upper Silesia Typhus Epidemic Report, where he elucidated the social-economic causes of diseases and deaths, in other words, explaining under which societal conditions morbidity and mortality arise (Virchow, [1848] 2006). Embracing Hegel's dialectical method in the analysis of health problems, Virchow presents a successful example of dialectical approach to biological and social issues in his report.
Master of the dialectical approach, Hegel, argued that life couldn't exist without disease; every organism is born with the "germ of death," and treatment sees disease not as the complete loss of health but rather as a conflict within or between physical forces.
However, Virchow, rejecting Hegelian idealism, embraced materialism. In his efforts to form a dialectical materialist approach in biology, he extensively utilized Friedrich Engels' work "The Condition of the Working Class in England" to demonstrate the relationship between poverty and disease (Engels, 1994).
