Philosophy Principles of sound reasoning - Essay Example

The principle of non-contradiction is a principle that is applicable in philosophical reasoning: It asserts that it is not correct to posit that something is correct while at the same time claiming it is correct. The discussion will attempt to explicate whether some of the commonly used tautologies are contradictory in nature. Additionally, it will explore on whether some tautologies are logically equivalent as well as provision of insights whether some contradictions are contingent. Moreover, the discussion will focus on elaboration of some contingents and determine whether they are logically equivalent in nature.

The corpus of logically equivalent tautologies entails a scenario where two different forms of statements have similar truth. On the other hand, the concept of tautology exists in compound statements that are usually true in nature no matter what circumstance it is presented. It is a fact that some tautologies are logically equivalent. It is a fact that some tautologies are usually logically equivalent. For example; this can be presented in the Venn diagram below: The Venn diagram below indicates a scenario where A represents animals with mammary glands and B represents all mammals.

The point of intersection represents A&B; meaning A can be B and B can be A. In this regard the first premise indicating that all mammals have mammary glands, which is valid. The second statement is also valid indicating that any animal with mammary glands are mammals. In philosophical dimensions, the aspect of contingency alludes to statements that seem possible untrue or even true when exposed to possible valuation. When a contingency is proposed it may not be necessarily false or to some extent necessarily true.

Contradictions are usually true statements that exhibit true nature or could be true in regard to the facet of communication. In this regard, all contradictions may be viewed and contingent in nature.
