A voice comes to one in the dark. Imagine.
To one on his back in the dark. This he can tell by the pressure on his hind parts and by how the dark changes when he shuts his eyes and again when he opens them again. Only a small part of what is said can be verified. As for example when he hears, You are on your back in the dark. Then he must acknowledge the truth of what is said. But by far the greater part of what is said cannot be verified. As for example when he hears, You first saw the light on such and such a day. Sometimes the two are combined as for example, You first saw the light on such and such a day and now you are on your back in the dark. A device perhaps from the incontrovertibility of the one to win credence for the other. That then is the proposition. To one on his back in the dark a voice tells of a past. With occasional allusion to a present and more rarely to a future as for example, You will end as you now are. And in another dark or in the same another devising it all for company. Quick leave him.’
Samuel Beckett, Company.
