| We puny individuals have only 75, 80 or 96 years to look forward which is still a snap in the impenetrableness of time. |
| There is an impenetrableness about the place, the people and the experience that Groning, for all his care, doesn't quite penetrate. |
| This impenetrableness, my dear, is to be put among the shades in his character. |
| The stars, the night, the dark blue of heaven hid the secret in their impenetrableness. |
