Next o'er his books his eyes began to roll, In pleasing memory of all he stole. - Alexander Pope

This is the Jew That Shakespeare drew.

"Blessed is the man who expects nothing, for he shall never be disappointed" was the ninth Beatitude which a man of wit (who, like a man of wit, was a long time in gaol) added to the eighth.

Be silent always when you doubt your sense;
And speak, though sure, with seeming diffidence:
Some positive, persisting fops we know,
Who, if once wrong, will needs be always so;
But you, with pleasure own your errors past,
And make each day a critic on the last.
