what kind of liberty does Jaques wishes about in act2 scene 7?

He wishes to have the freedom to say anything he likes without fear of repercussion; just like the fool who jests.

It is my only suit,

Provided that you weed your better judgments

Of all opinion that grows rank in them

That I am wise. I must have liberty

Withal, as large a charter as the wind,

To blow on whom I please, for so fools have.
