Why Is Logic Both an Art and a Science?

Logic is a liberal art as well as a science when the art form is used speculatively. Educators support this statement, saying the goal of speculative logic is to realize a truth, which also results in action. Therefore, logicians use the science of logic to direct their thinking to demonstrate a truth.

Cardinal Mercier of the University of Notre Dame says that logic can also be considered a practical science that directs people's thinking. Citing St. Thomas, the cardinal quotes the saint, "In speculative matters the rational dialectic science is one thing [while] . . . the demonstrative, another."

Therefore, logic, when utilized as an art, is meant to demonstrate what a person is trying to convey. Cardinal Mercier adds that some individuals, specifically those who define logic as an art, believe it is speculative rather than practical. The cardinal states that "Logic is also an art, if we understand it as being a body of rules that will guide us toward an eventual activity."

Leo Tolstoy supported the definition of logic as art by saying that this type of reasoning is contingent on one person receiving another individual's feeling of expression. So, in order to consider logic as art, an action must occur that is subordinate to a person's reasoning and thinking.
