The phrase signifies a commitment to empirical evidence and independent verification, rather than blind adherence to authority or dogma. It emphasizes the importance of direct observation and experimentation in the pursuit of knowledge. A practical application involves researchers independently replicating experimental results to confirm their validity before accepting them as established facts.
Its value lies in fostering critical thinking and promoting objective evaluation in any field of study or endeavor. Historically, it represents a departure from reliance on traditional doctrines and a move toward scientific methodology. This approach encourages questioning established norms and seeking validation through verifiable data, thus leading to more robust and reliable conclusions.
