At the behest of logic, a deduction will be that argument in which the conclusion is inferred, yes or Yes, from the premises proposed. Meanwhile, deductive reasoning is the kind of reasoning that, in general, of a general premise, to the particular, i.e. something that is general is deducing particular conclusions. Note, that deductive reasoning will be considered as valid if the conclusion is arrived at which derive from the premise of which broke, for example: all men have feelings, Juan is a man, so John has feelings. It may happen that the premise is not true, although the form of the argument will remain valid in spite of this. A distinctive feature of the valid deductive reasoning is that at the conclusion it will something unprecedented and independent with respect to those issues raised promptly on the premise. The truth of the conclusion in a deductive reasoning is conditional: correction of the proposed argument and to the truth of its premise. In this type of reasoning the truth of the same value rests in one hundred percent on its premises. On the sidewalk opposite the deductive reasoning we have inductive reasoning, which on the contrary of the anterior part of the particular to the general. From private premises, resulting from the observation of a phenomenon, inductive reasoning to reach a conclusion of General characteristics. In this type of reasoning the conclusion is beyond the proposal of the premises. Inductive reasoning we use it constantly in our daily lives, now well, we must recognize the limits mentioned has in this regard and then as its form is not based on a profound test is incomplete, therefore, the conclusion will be nothing more than a guess; Meanwhile, to increase the chances of accuracy how complete is the information collected. These arguments proved to be very used in the antiquity of the world by the leading philosophers.
