“It is error only, and not truth, that shrinks from inquiry.”
“Sometimes a clearly defined error is the only way to discover the truth”
“Truth can understand error, but error cannot understand truth.”
“That an error made on your own is safer than ten truths accepted on faith, because the first leaves you the means to correct it but the second destroys your capacity to distinguish truth from error.”
“What is true today may not be true ten years from now; there is more truth, more certainty in the inquiry "What if?" than in the definite "It is”
“Men must fumble awhile with error to separate it from truth, I think- as long as they don't seize the error hungrily because it has a pleasanter taste.”
