Summary
This quote suggests that when someone is completely consumed by an idea or belief, they become impervious to logical arguments or counterpoints. Possession of a strong idea often generates an intense emotional attachment, which can hinder their ability to objectively consider alternative perspectives. No matter how persuasive or rational the opposing arguments may be, a person consumed by an idea will hold steadfastly to their own viewpoint. It highlights the influence of strong conviction and the potential limitations it imposes on open-mindedness and impartial reasoning.
