Context: She that would raise a noble love must find
Ways to beget a passion for her mind;
She must be that which she to the world would seem,
For all true love is grounded on esteem:
Plainness and truth gain more a generous heart
Than all the crooked subtleties of art.

Context: American traditions and the American ethic require us to be truthful, but the most important reason is that truth is the best propaganda and lies are the worst. To be persuasive we must be believable; to be believable we must be credible; to be credible we must be truthful. It is as simple as that.
Lecture to the Royal Aeronautical Society (1913)
“He who has the truth at his heart need never fear the want of persuasion on his tongue.”
