A man’s whole life is taxed for the least thing well done.

Context

“Hussein Effendi praised the epistolary style of Ibrahim Pasha to the French traveller Botta, because of “the difficulty of understanding it; there was,” he said, “but one person at Jidda, who was capable of understanding and explaining the Pasha’s correspondence.” A man’s whole life is taxed for the least thing well done. It is its net result. Every sentence is the result of a long probation. Where shall we look for standard English, but to the words of a standard man? The word which is best said came nearest to not being spoken at all, for it is cousin to a deed which the speaker could have better done.” source
