Common-sense

[L:63] Common sense or common understanding can be used as "a touchstone to discover the mistakes of the technical employment of the understanding"; through common sense one can "orient oneself in thinking"; common sense can be used as "a test of judging the correctness of" speculative understanding. Kant associated common sense with "the broadened maxim", one of three maxims for avoiding error, which enjoins one "to think oneself in the place of another....[by] putting oneself into others' viewpoints."
