If appearances are deceitful, then they do not deserve any confidence when they assert what appears to them to be true.
Favour is deceitful, and beauty is vain.
This world is all a fleeting show,
For man's illusion given;
The smiles of joy, the tears of woe,
Deceitful shine, deceitful flow,—
There's nothing true but Heaven.
What mighty ills have not been done by woman!
Who was 't betrayed the Capitol?—A woman!
Who lost Mark Antony the world?—A woman!
Who was the cause of a long ten years' war,
And laid at last old Troy in ashes?—Woman!
Destructive, damnable, deceitful woman!
