SYNONYMS DISCRIMINATED*

[ocr errors]

Disbelief, n., denial of belief, incredulity.

Syn. : unbelief, scepticsm, infidelity.
Ant. : faith, credence, trust, assent.

Syn. dis. : Unbelief is negative ; disbelief is
positive; unbelief may arise from want of
knowledge, but disbelief rejects as false. Un-
belief is the absence, disbelief the refusal of
credit. Incredulity and infidelity are used, the
former to signify absence of belief where it is
possible, the latter absence of belief where it is
right. Incredulity may be therefore right
where it denotes a proper reluctance of assent
to what ought not to be easily believed, or not
believed at all; infidelity is, by the force of the
term, wrong. Scepticism implies disbelief or
inability to believe, and commonly expresses a
doubting of the truth of revelation or of the
Christian religion.
Distinguished, adj., noted or celebrated for

some superior or extraordinary quality ;

marked, famous. Syn. : eminent, illustrious, conspicuous, prominent.

Ant. : common, commonplace, obscure, ordinary.

Syn. dis. : Distinguished directly relates to persons and to deeds, and to persons for the sake of their deeds : it conveys the idea of social eminence or prominence as the result of public services rendered, or merit publicly exhibited. Eminent is only employed of persons — those who stand above their fellows: when things stand out conspicuously they are called prominent; e.g., the eminent characters of history, and the prominent events. Illustrious is used strictly only of persons, inasmuch as human acts or character can alone make things illustrious, as being the agents or recipients of what is illustrious ; thus we speak of illustrious heroes, nobles, titles. If we speak of illustrious deeds or events, it is as being done or brought about by human agency. Docile, adj. (do'-sîl or dos'-11), easily instructed

or managed ; teachable; willing or ready to

learn. Syn, : tractable, amenable, compliant, tame.

Ant. : stubborn, dogged, intractable, ob stinate,

Syn. dis. : Docile (lit. easy to teach (im. plies more than tractable (easy to handle): tractable denotes no more than the absence of refractoriness, docile the actual quality of meet. ness. Amenable is commonly used of human
