COMMON SENSE , med. jur. When a person possesses those perceptions, associations and judgments, in relation to persons and things, which agree with those of the generality of mankind, he is said to possess common sense. On the contrary, when a particular individual differs from the generality of persons in these respects, he is said not to have common sense, or not to be in his senses. 1 Chit. Med. Jur. 334.
