"Namely, we have no right to believe a thing true because everybody says so unless there are good grounds for believing that some one person at least has the means of knowing what is true, and is speaking the truth so far as he knows it"
About this Quote
The specific intent is disciplinary. As a mathematician steeped in proof, Clifford imports a proof-like demand into everyday ethics: don`t let your mind become a rumor mill. The subtext is that "everybody says so" is not neutral; it is a power move. It launders uncertainty into certainty, lets institutions and majorities smuggle claims past scrutiny, and flatters the believer with the safety of belonging. His "no right" frames credulity as moral failure, not merely intellectual error, because bad beliefs don`t stay private; they steer votes, policies, and prejudices.
Context matters: Victorian Britain was an age of scientific authority and religious argument, of expanding mass media and respectable opinion. Clifford is writing against inherited dogma and the prestige of received wisdom, insisting that modern life demands epistemic accountability. In today`s terms, he is offering an anti-virality principle: before you share, repeat, or assent, ask who actually knows - and whether the pipeline from fact to you has been kept clean.
