I didn't. Berger himself was a Marxist and his analysis was often political (he wrote a lot but none of it made the impact as the Ways of Seeing which did become influencial in media and art criticism), but the Ways of Seeing largely talks about the methodology. He cites studies in the first essay to demonstrate how the context of a visual piece changes based on where the person sees it. His analyses didn't become mainstream and stayed confined mostly to Marxist circles (and he still didn't make claims about sexual preferences being formed by the culture), his methodology did though.
