Description in English: Logical reasoning is due to a chain of premises in which the rules accepted as valid are applied link by link until arriving at conclusions. This process is referred to as a logical consequence. The book is addressed to middle and high school students, teachers, and professionals in general. Focused on the natural deduction system, we critically emphasize the close relationship between symbolic language and the logic of natural language. Both languages, within their limits, are intertwined and coupled with each other by the rules of inference, validity, argumentation, deduction, and testing, although few clarify how they intertwine, or whether symbolism comes from formalizing rules of the mind, or whether their relationship is merely conventional.
