Definitions

  1. adv. For a still stronger reason; all the more.

Century Dictionary and Cyclopedia

  1. For a still stronger reason; all the more. A phrase used in, and sometimes employed as the designation of, a kind of argument, which concludes either that something does not take place, because the causes which alone could bring it to pass operate still more strongly in another case without producing that effect; or that something does take place, because causes much weaker than those which operate to bring it about are effective in another case. An argument of the latter kind is the following: “If God so clothe the grass of the field, which to-day is and to-morrow is cast into the oven, shall he not much more clothe you, O ye of little faith?” Mat. vi. 30.
