Influence, Authority, Ascendancy, Control, Sway, Domination, may all apply to persons or things, but seem primarily to belong to persons. Influence and authority imply moral power; the others may do so, and are considered to do so here. The words are arranged in the order of their strength. Influence may be small; it is wholly apart from the power of office; the word expresses the extent to which one affects the conduct or character of others simply by their deference to him on account of his station, wealth, ability, character, etc. Authority is, in this connection, influence amounting to a recognized right to command: as, the authority of age, wisdom, experience. It is presumably rightful, while the other words often express undue or unwholesome weight or power. Ascendancy is overmastering influence, supremacy by influence; the word is often used in a bad sense: as, the ascendancy of cunning over simplicity. Control is complete or successful and continued authority: as, his control over the convicts was maintained without resort to force. Sway is, by its derivation, control over that which may be viewed as a weighty or massive object; hence, a solid or powerful or controlling influence. Domination, as it may be an absolute and tyrannical rule, may also be an absolute and tyrannical influence or ascendancy: as, he was really under the domination of those whom he thought his servants or tools.
