high on the Tone Scale. High-toned individuals think wholly into the future. They are extroverted toward their environment. They clearly observe the environment with full perception unclouded by undistinguished fears about the environment. They think very little about themselves but operate automatically in their own interests. They enjoy existence. Their calculations are swift and accurate. They are very self-confident. They know they know and do not even bother to assert that they know. They control their environment. See also Tone Scale in this glossary.—2D Tapes Glossary Final approval 22 Mar 90
