Tactfulness comes from our consideration for one another, and that consideration comes from our feeling, our sympathy for one another. What is consideration? Consideration is feeling "all that is displeasing, distasteful, disagreeable to me - I must not cause it to another." From this sense tact develops as wisdom. A man may be most learned, most capable, most influential, and yet not be tactful. Tactfulness is the sign of the great ones; great statesmen, kings, leaders, heroes, the most learned men, the great servers of humanity were tactful. They won their enemies, their worst adversaries, by their tact; they accomplished the most difficult things in life by the power of tact.
