Logic is the study of the methods and principles used to distinguish correct from incorrect reasoning. It involves the study of the relations that lead to the acceptance of a conclusion on the basis of premises.

Lewis Carroll, the author of Alice’s Adventures in Wonderland, advocated teaching logic to children. On the teaching of logic and logic graphs to children, the great American philosopher and logician, Charles Sanders Peirce, wrote: “The aid that the system of graphs thus affords to the process of logical analysis, by virtue of its own analytical purity, is surprisingly great, and reaches further than one would dream. Taught to boys and girls before grammar, to the point of thorough familiarization, it would aid them through all their lives. “
