After all, I concluded that at Feynman's hypotetical example there's no electroscope connected to the capacitor. If there was, the charges on the plate wouldn't remain unchanged when the dielectric is put between the plates. | |

That means, of course, that the voltage is lower for the same charge. But the voltage difference is the integral of the electric field across the capacitor; so we must conclude that inside the capacitor, the electric field is reduced even though the charges on the plates remain unchanged. | |
