When Bishop Berkeley said "there was no matter,"[562]And proved it—'t was no matter what he said:

They say his system 't is in vain to batter,

Too subtle for the airiest human head;

And yet who can believe it? I would shatter

Gladly all matters down to stone or lead,

Or adamant, to find the World a spirit,

And wear my head, denying that I wear it.
