Kenneth J Arrow said this quote

“ I have always preferred the contemplative to the active life. I prefer the freedom to see matters from several viewpoints, to appreciate ironies, and indeed to change my opinion as I learn something new. To be politically active means to surrender this freedom. I say nothing against activism for others. It is only through the committed that necessary changes come. But each to his own path. [A Cautious Case for Socialism, Dissent Magazine, 1978] ”
