Doubt Quote by Mark Clark
““Charles Darwin himself recognized this problem and feared it when he wrote hauntingly: “Within me the horrid doubt always arises whether the convictions of a man’s mind, which has been developed from the mind of lower animals, are of any value or at all trustworthy.”40 The problem being, of course, that Darwin’s theory itself was the conviction of man’s mind, and thus by his own logic, he couldn’t trust it.””
