In "The Proud Tower: A Portrait of the World Before the War, 1890-1914," author Barbara W. Tuchman conveys a piece of advice given to young Samuel Gompers, suggesting that he should take lessons from socialism without becoming a member of its ranks. This counsel highlights the importance of understanding different ideologies and perspectives, allowing one to be informed while maintaining independence from any specific movement or doctrine.

This advice can be widely applicable across various fields and disciplines, encouraging individuals to critically assess different theories and practices. Engaging with diverse thoughts can lead to greater insights and enhance one's own viewpoints, provided one remains discerning and does not become overly committed to any single ideology.
