I asked each in turn for their thoughts. They were a bird, a house, a horse, &c., all visible objects.

I said, "All these things can be seen when they are before you; but can you see the thought?"

Some answered "Yes" to this, which I found meant that they could see the image of the thing in the mind; others said "No."

"Can you see your thinking?"

"No."

"Can you not send your thoughts out into the country, where you have sometimes taken a ride?"

"Yes."

"Can you see, smell, hear, taste, or touch your mind?"

"No."

"But is not mind a real thing? Have not you a mind that you think with?"
