So far as I can see, all political thinking for years past has been vitiated in the same way. People can foresee the future only when it coincides with their own wishes, and the most grossly obvious facts can be ignored when they are unwelcome.

Summary

This quote suggests that political thinking is often biased by personal desires, leading to a distorted view of the future. The author argues that people tend to only foresee outcomes that align with their own wants, disregarding inconvenient facts. This assertion implies that political analysis is often clouded by subjective perspective rather than objective reasoning. Ultimately, it serves as a reminder to critically examine one's own biases and consider the broader picture for a more comprehensive understanding of political matters.
