Quote from ‘Grand Logic 1893: Division III. Substantial Study of Logic Chapter VI. The Essence of Reasoning’

Quote: 

St. Thomas Aquinas [Summa totius logicæ Aristotelis (Opusculum 48)] divides the operations of the Understanding in reference to the logical character of their products into
     Simple Apprehension,
     Judgment, and
     Ratiocination, or Reasoning. [—]

Ratiocination or reasoning produces inferences or reasonings, which are expressed by argumentations, as, ” I think, therefore I must exist,” “Enoch, being a man, must have died; and since the Bible says he did not die, not everything in the Bible can be true.”
