[1913 Webster] I'll give him reasons for it. --Shak. [1913 Webster] The reason of the motion of the balance in a wheel watch is by the motion of the next wheel. --Sir M. Hale. [1913 Webster] This reason did the ancient fathers render, why the church was called "catholic." --Bp. Pearson. [1913 Webster] Virtue and vice are not arbitrary things; but there is a natural and eternal reason for that goodness and virtue, and against vice and wickedness. --Tillotson. [1913 Webster] 2. The faculty or capacity of the human mind by which it is distinguished from the intelligence of the inferior animals; the higher as distinguished from the lower cognitive faculties, sense, imagination, and memory, and in contrast to the feelings and desires. Reason comprises conception, judgment, reasoning, and the intuitional faculty. Specifically, it is the intuitional faculty, or the faculty of first truths, as distinguished from the understanding, which is called the discursive or ratiocinative faculty. [1913 Webster] We have no other faculties of perceiving or knowing anything divine or human, but by our five senses and our reason. --P. Browne. [1913 Webster] In common and popular discourse, reason denotes that power by which we distinguish truth from falsehood, and right from wrong, and by which we are enabled to combine means for the attainment of particular ends. --Stewart. [1913 Webster] Reason is used sometimes to express the whole of those powers which elevate man above the brutes, and constitute his rational nature, more especially, perhaps, his intellectual powers; sometimes to express the power of deduction or argumentation. --Stewart. [1913 Webster] By the pure reason I mean the power by which we become possessed of principles. --Coleridge. [1913 Webster] The sense perceives; the understanding, in its own peculiar operation, conceives; the reason, or rationalized understanding, comprehends. --Coleridge. [1913 Webster] 3.

[1913 Webster] I was promised, on a time, To have reason for my rhyme. --Spenser. [1913 Webster] But law in a free nation hath been ever public reason; the enacted reason of a parliament, which he denying to enact, denies to govern us by that which ought to be our law; interposing his own private reason, which to us is no law. --Milton. [1913 Webster] The most probable way of bringing France to reason would be by the making an attempt on the Spanish West Indies. --Addison. [1913 Webster] 4. (Math.) Ratio; proportion. [Obs.] --Barrow. [1913 Webster] By reason of, by means of; on account of; because of. "Spain is thin sown of people, partly by reason of the sterility of the soil." --Bacon. In reason, In all reason, in justice; with rational ground; in a right view. [1913 Webster] When anything is proved by as good arguments as a thing of that kind is capable of, we ought not, in reason, to doubt of its existence. --Tillotson. [1913 Webster] It is reason, it is reasonable; it is right. [Obs.] [1913 Webster] Yet it were great reason, that those that have children should have greatest care of future times. --Bacon. [1913 Webster] Syn: Motive; argument; ground; consideration; principle; sake; account; object; purpose; design. See Motive, Sense.
