INFERENCE or Reasoning is that act of Pure Thought whereby one Judgment is derived from another, or from two others. The Judgment from which another is deduced is called the Premise; and that which is derived is called the Conclusion. If the Conclusion is drawn directly from one Premise only, without the aid either of an Intuition or another Judgment, it is said to be an Immediate Inference. Thus, from the Premise that No quadruped is rational, I know at once, or by Immediate Inference,--that is, by an act of Pure Thought,--that Every quadruped is irrational, and that No rational thing is a quadruped. If the Conclusion can be drawn only through the intervention of a third Judgment,--in other words, if two Premises are necessary,--the result is a Mediate Inference, or Syllogism. But in either case, the act of Reasoning or Inference, whether Mediate or Immediate, is simple, being one indivisible act of mind. The Premises are considered as given, and their truth is taken for granted; the Inference is the act of deduction, or drawing out the Conclusion from the Premises, and this act is necessarily simple. If it is performed in accordance with the Laws of Pure Thought, it is apodeictic or absolutely certain, as any opposite Conclusion would be Contradictory and absurd. In respect to their Matter, both the Premises and the Conclusion may be false; and yet the Form of Inference, or the transition from one to the other, may be intuitively true. Thus, the Mediate Inference, Everything material is mortal; The Soul is material; Therefore the Soul is mortal;--is false in each of its three Judgments. Yet its Conclusion is as correctly dra...
