In page Helena Sheehan:

"

As a philosopher and historian of science, Sheehan writes from a Marxist perspective. She argues that Marx and Engels shared fundamentally the same view on the philosophy of science[4] and written critically of Lysenkoism and Stalin's impact on scientific development, while stressing the necessity of understanding such trends in full socio-historical context.[citation needed] She is a strong critic of both positivism and postmodernism.[citation needed]
