Persons may contend either from mere ill will or self-interest, or from the highest motives; "That ye should earnestly contend for the faith which was once delivered to the saints," Jude 3. To argue (L. arguo, show) is to make a matter clear by reasoning; to discuss (L. dis, apart, and quatio, shake) is, etymologically, to shake it apart for examination and analysis. Demonstrate strictly applies to mathematical or exact reasoning; prove may be used in the same sense, but is often applied to reasoning upon matters of fact by what is called probable evidence, which can give only moral and not absolute or mathematical certainty. To demonstrate is to force the mind to a conclusion by irresistible reasoning; to prove is rather to establish a fact by evidence; as, to prove one innocent or guilty. That which has been either demonstrated or proved so as to secure general acceptance is said to be established. Reason is a neutral word, not, like argue, debate, discuss, etc., naturally or necessarily implying contest. We reason about a matter by bringing up all that reason can give us on any side. A dispute may be personal, fractious, and petty; a debate is formal and orderly; if otherwise, it becomes a mere wrangle.(verb)
While the cause of any event, act, or fact, as commonly understood, is the power that makes it to be, the reason of or for it is the explanation given more..While the cause of any event, act, or fact, as commonly understood, is the power that makes it to be, the reason of or for it is the explanation given by the human mind; but reason is, in popular language, often used as equivalent to cause, especially in the sense of final cause. In the statement of any reasoning, the argument may be an entire syllogism, or the premises considered together apart from the conclusion, or in logical strictness the middle term only by which the particular conclusion is connected with the general statement. But when the reasoning is not in strict logical form, the middle term following the conclusion is called the reason; thus in the statement "All tyrants deserve death; Cæsar was a tyrant; Therefore Cæsar deserved death," "Cæsar was a tyrant" would in the strictest sense be called the argument; but if we say "Cæsar deserved death because he was a tyrant," the latter clause would be termed the reason. Compare CAUSE; REASON, v.; MIND; REASONING.(noun)
talk over conjecturally, or review in an idle or casual way and with an element of doubt or without sufficient reason to reach a conclusion (verb.communication)
derivation (.... is derived from reason)
a justification for something existing or happening(noun.communication)
