Quote by Leonardo DaVinci
Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory.
This quote suggests that relying solely on the authority of others during an argument or debate is a weak approach. It implies that true intelligence lies in using one's own ability to reason and think critically instead of solely relying on past information or what others say. The quote calls for individuals to cultivate and utilize their own intellect rather than just relying on what they have memorized or heard.
