"And by my philosophy, O King, I am certified concerning these apparitions which you have raised for me, that they be illusions and phantasms only, able to terrify the soul indeed of him that knoweth not divine philosophy, but without bodily power or essence. Nor is aught to fear in such, save the fear itself wherewith they strike the simple."
Then said the King, "By what token knowest thou this?"
And the Lord Gro made answer unto him, "O King, as a child weaveth a daisy-chain, thus easily did you conjure up these shapes of terror. Not in such wise fareth he that calleth out of the deep the deadly terror indeed; but with toil and sweat and with straining of thought, will, heart, and sinew fareth he."
The King smiled. "Thou sayest true. Now, therefore, since phantasmagoria maketh not thy heart to quail, I present thee a more material horror."
