So much he’s seen of baseness in the mind,
That, while a friend to man, he scorns mankind;
He knows the human heart, and sees with dread,
By slight temptation, how the strong are led;
He knows how interest can asunder rend
The bond of parent, master, guardian, friend,
To form a new and a degrading tie
’Twixt needy vice and tempting villainy.
Sound in himself, yet when such flaws appear,
He doubts of all, and learns that self to fear;
For where so dark the moral view is grown,
A timid conscience trembles for her own;
The pitchy-taint of general vice is such
As daubs the fancy, and you dread the touch.
