A foolish friend may cause more woe
Than could, indeed, the wisest foe.

a man is judged by his friends, for there was never agreement between wise men and fools.

Love is the wisdom of the fool and the folly of the wise.

Love is the foolishness of men, and the wisdom of God.

Though all one's life a fool associates with a wise person,one no more comprehends the Truth than a spoon tastes the flavor of the soup.

Do not let me hear
Of the wisdom of old men, but rather of their folly,
Their fear of fear and frenzy, their fear of possession,
Of belonging to another, or to others, or to God.
The only wisdom we can hope to acquire
Is the wisdom of humility: humility is endless.

If it was not for the company of fools, a witty man would often be greatly at a loss.

Fools make feasts and wise men eat them.

I am two fools, I know,
For loving, and for saying so
In whining poetry;
But where's that wiseman, that would not be I,
If she would not deny?
Then as th' earth's inward narrow crooked lanes
Do purge sea water's fretful salt away,
I thought, if I could draw my pains
Through rhyme's vexation, I should them allay.
Grief brought to numbers cannot be so fierce,
For he tames it, that fetters it in verse.

But when I have done so,
Some man, his art and voice to show,
Doth set and sing my pain;
And, by delighting many, frees again
Grief, which verse did restrain.
To love and grief tribute of verse belongs,
But not of such as pleases when 'tis read.
Both are increased by such songs,
For both their triumphs so are published,
And I, which was two fools, do so grow three;
Who are a little wise, the best fools be.

A fool is known by his speech, and a wise man by silence.

Who is the man who can speak to the strong?
Where is the fool who can talk to the wise?
Men who are dead now have learnt this long,
Bitter is wisdom that fails when it tries.

Silence is the virtue of fools.

The wisest men follow their own direction
And listen to no prophet guiding them.
None but the fools believe in oracles,
Forsaking their own judgment.

Friendship is the wine of life.
