Gorky's description of Tolstoy is typical: 'With sharp eyes, from which neither a single pebble nor a single thought could hide itself, he looked, measured, tested, compared.' Or again, his eyes are 'screwed up as though straining to look into the future'.
Equally typical is Trotsky's description of Lenin:
When Lenin, his left eye narrowed, receives a wireless containing a speech he resembles a devilishly clever peasant who does not let himself be confused by any words, or deluded by any phrases. That is highly intensified peasant shrewdness, lifted to the point of inspiration.

An infant of two or three months will smile at even half a painted dummy face, if that half of the face is fully represented and has at least two clearly defined points or circles for eyes; more the infant does not need, but he will not smile for less. The infant's instinctive smile seems to have exactly that purpose which is its crowning effect, namely, that the adult feels recognized, and in return expresses recognition in the form of loving and providing.

Doubt is the brother of shame.
