The Illusion of A Chair (Poem)

Consider this wooden object.

This is a chair. You say.

But is it? I ask. What makes it so?

This! And you sit upon it.

Ah, I see. But please arise.

I place my tea cup and notebook upon it.

Now, still a chair? Or has it transformed into a table?

I remove them.

Would you please retrieve that book from a high shelf?

You then stand upon the sturdy item.

It has become a stepladder.

What magic is this?

Thus is all.
