Understanding is the heartwood of well-spoken words.

To use the same words is not a sufficient guarantee of understanding; one must use the same words for the same genus of inward experience; ultimately one must have one's experiences in common.

When words are scarce they are seldom spent in vain.

There are tones of voices that mean more than words.

Words spoken cannot be recalled so think twice before you speak.

Men standing in opposite hemispheres will converse and deride each other and embrace each other, and understand each other's language.
