It is wrong for a man to say that he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty.
A well-worn adage advises those who set out upon a great enterprise to count the cost, yet some of the greatest enterprises have succeeded because the people who undertook them did not count the cost.
Interpretation
What this quote means
Sometimes, great accomplishments happen when individuals ignore the potential risks or costs involved.
This quote by Thomas Huxley reflects on the paradox of undertaking significant endeavors. While conventional wisdom suggests a careful assessment of potential costs before starting a project, history shows that many successful ventures are rooted in a boldness that overlooks these costs. This disregard allows individuals to pursue their passions and dreams with an unburdened spirit, often leading to revolutionary outcomes that might not have been attempted if the costs were fully acknowledged.
