"In like manner, if I let myself believe anything on insufficient evidence, there may be no great harm done by the mere belief; it may be true after all, or I may never have occasion to exhibit it in outward acts"

This quote by William Kingdon Clifford is stressing the significance of evidence when forming beliefs. He is suggesting that if we believe something without sufficient proof, it may not be harmful in itself, as it might turn out to be true, or we might never ever need to act upon it. However, Clifford is cautioning versus forming beliefs without evidence, as it can cause incorrect conclusions and potentially hazardous actions. He is suggesting that we should take care to only type beliefs based on evidence, as this will assist us to make more informed decisions and avoid possible harm. This quote is a reminder to think critically and to be mindful of the proof we utilize to form our beliefs.
