reasonable, temperate, judicious, just, cool, steady, calm. Moderate, temperate, judicious, reasonable all stress the avoidance of excess—emotional, physical, intellectual, or otherwise. Moderate implies response or behavior that is by nature not excessive: a moderate drinker, a moderate amount of assistance.
Temperate, interchangeable with moderate in some general uses, usually stresses the idea of caution, control, or self-restraint: a surprisingly temperate response to the angry challenge.
Judicious emphasizes prudence and the exercise of careful judgment: a judicious balance between freedom and restraint; judicious care to offend neither side.
Reasonable suggests the imposition or adoption of limits derived from the application of reason or good sense: a reasonable price; a reasonable amount of damages allotted to each claimant. 2.
