"In the present epoch of struggle between two worlds the two opposing and antagonistic trends penetrating the foundations of nearly all branches of biology are particularly sharply defined"
About this Quote
The rhetoric is engineered for institutional control. Notice the vagueness: no trends are named, no evidence offered, no mechanisms specified. That’s not a bug; it’s the feature that lets ideology do the work of argument. “Sharply defined” performs certainty while avoiding the risk of falsification. You’re meant to feel that history has already judged the matter, and your job is to get on the correct side of it.
Context does the rest. Lysenko rose in Stalin’s USSR by denouncing Mendelian genetics as “bourgeois” and promoting a politically convenient heredity model that promised rapid agricultural transformation. The “two worlds” aren’t just scientific paradigms; they’re class enemies. In that climate, describing biology as a front line helped justify purges of dissenting geneticists, the rewriting of curricula, and the substitution of party alignment for peer review.
The subtext is chillingly practical: disagreement isn’t error, it’s sabotage. By turning a methodological dispute into an existential struggle, Lysenko’s language makes coercion sound like historical necessity.
