Escape from such confusion can hardly come from the accepted formulas of the dictionaries. Their descriptions or periphrases of corruption are in general much too broad for use in exact discussion. Bribery, indeed, is defined with sufficient sharpness by the _Century Dictionary_ as “a gift or gratuity bestowed for the purpose of influencing the action or conduct of the receiver; especially money or any valuable consideration given or promised for the betrayal of a trust or the corrupt performance of an allotted duty, as to a fiduciary agent, a judge, legislator or other public officer, a witness, a voter, _etc._” Corruption, however, is by no means synonymous with bribery. The latter is narrower, more direct, less subtle. There can be no bribe-taker without a bribe-giver, but corruption can and frequently does exist even when there are no personal tempters or guilty confederates. A legislator may be approached by a person interested in a certain corporation and may be promised a definite reward for his favourable vote on a measure clearly harmful to the public interest but calculated to benefit the corporation concerned. If the bargain be consummated it is unquestionably a case of bribery, and the action involved is also corrupt. But, if current reports are to be believed, it sometimes happens that legislators, acting wholly on their own initiative and regardless of their duty to the state, vote favourably or unfavourably on pending bills, endeavouring at the same time to profit financially by their action, or by their knowledge of the resultant action of the body to which they belong, by speculation in the open market. In the latter instance they have not been approached by a personal tempter, and the brokers whom they employ to buy or sell may be ignorant of the motives or even of the identity of their patrons. Clearly this is not bribery, but equally clearly it is corrupt. The distinction is perhaps sufficiently important to justify the coinage of the term “auto-corruption” to cover cases of the latter sort.[15] Corruption in the widest sense of the term would then include both bribery and auto-corruption, and may be defined as _the intentional misperformance or neglect of a recognised duty, or the unwarranted exercise of power,_[16] _with the motive of gaining some advantage more or less directly personal_.
