We then apply certain rules to the sentences until we are left with only atomic statements. Natural deduction does just that. When we speak informally, we use many kinds of valid arguments. (I'll give some examples in a moment.) Natural deduction makes these familiar forms of argument exact. It also organizes them in a system of valid arguments in which we can represent absolutely any valid argument. The concept of natural deduction follows a truly natural progression, establishing the relationship between a noteworthy systematization and the interpretation of logical signs. Natural Deduction.

Natural Deduction Constructing truth trees is not the only method for determining whether arguments are valid; another method is known as natural deduction. To prove an argument is valid using the truth tree method, we list the premises and the negated conclusion. We then apply certain rules to the sentences until we are left with only atomic statements.
