The Archbishop came to Scetis one day. The brethren who were assembled said to Abba Pambo, ‘Say something to the Archbishop, so that he may be edified.’ The old man said to them, ‘If he is not edified by my silence, he will not be edified by my speech.’

Sayings of the desert fathers, translated by Benedicta Ward.

Those who know, do not speak; those who speak, do not know.

Tao Te Ching

Whereof one can not speak, thereof one must be silent.

Ludwig Wittgenstein, Tractatus Logico-Philosophicus

But Jesus kept silent and did not answer.

Mark 14:61

There is not much to add here; I think these quotes pretty much cover it.

TAKE AWAY: The more words you need, the less likely it is that you know what you’re talking about.
