Let us assume the existence of beds and tables.

There is one idea of a bed, or of a table, which the maker of each had in his mind when making them; he did not make the ideas of beds and tables, but he made beds and tables according to the ideas.

And is there not a maker of the works of all workmen, who makes not only vessels but plants and animals, himself, the earth and heaven, and things in heaven and under the earth?
He makes the Gods also.

'He must be a wizard indeed!' But do you not see that there is a sense in which you could do the same?
You have only to take a mirror, and catch the reflection of the sun, and the earth, or anything else--there now you have made them.

'Yes, but only in appearance.' Exactly so; and the painter is such a creator as you are with the mirror, and he is even more unreal than the carpenter; although neither the carpenter nor any other artist can be supposed to make the absolute bed.
