Logic FROM 3

Chapter 1 INTRODUCTION TO LOGIC

TYPES OF LOGIC
  1. Deductive (Formal) Logic

It concerns itself with the principles and methods of self consistency is thinking and not with the content of a judgment. It does not concerns itself with the conclusion arrived at by somebody in reasoning but with the method used to reach that conclusion.

  1. Inductive (Material) Logic

It concerns itself with the content of a judgment. It seeks to organize into a systematic role fact which appears to be isolated, fragmentary and discrepant. In inductive we infer a general rule from particular cases. An inductive argument is one whose conclusion is claimed to follow from its premises only with probability. These probabilities being matters of degrees and dependent upon what else maybe in the cases. This means that, if the premises are true, the conclusion is likely true than false.

 

  1. Analytical Logic

It looks at the various elements that make up a compound sentence or an idea. Example: In the statement “There are two elements”.

  • Conditional: One will only have rabies when biting by a dog.
  • Cause-Effect Relations: That rabies is the effect of dog bit which is the cause.
  1. Symbolic Logic

It is the form of history in which symbols are used. Symbolic logic is concerned with the value of true functional compound statement through the use of logical notations. These special symbols help to exhibit in greater clarity the logical structures of preposition and the argument whose form may not be very precise in the ordinary language.
