Synonym: Probity, integrity.
Probity denotes unimpeachable honesty and virtue, shown especially by the performance of those obligations, called imperfect, which the laws of the state do not reach, and can not enforce. Integrity denotes a whole-hearted honesty, and especially that which excludes all injustice that might favor one's self. It has a peculiar reference to uprightness in mutual dealings, transfer of property, and the execution of trusts for others.
Origin: F. Probite, fr. L. Probitas, fr. Probus good, proper, honest. Cf. Prove.
