"The ultimate court of appeal is observation and experiment... not authority"

This quote by Thomas Huxley suggests that observation and experimentation ought to be the main source of understanding and truth, rather than depending on authority. Huxley was a proponent of the scientific approach, which counts on empirical evidence and experimentation to reason. He thought that the only method to genuinely comprehend the world was to observe it and check it, instead of counting on the opinions of experts or authorities. This quote is a reminder that understanding need to be based on proof, not on the viewpoints of those in power. It encourages us to think seriously and to question the status quo. By counting on observation and experimentation, we can gain a better understanding of the world and make more informed decisions.
