Induction is probabilistic inference. In an inductive argument (syllogism), the premise or proof leads to a conclusion more likely, while the deductive argument presuppositions come to the fore, presenting the conclusion as true by necessity.
Charles Peirce emphasizes that in our inquiries the three forms of inference – induction, deduction, abduction – work together.
Abduction is the process by which a hypothesis is formed, the deduction is the process by which the necessary consequences of a hypothesis are established, and induction is the process by which they are tested.
Induction is often used more freely and logically incorrectly to denote the process of transition from individual truth to general and even universal truth.
In parallel with this meaning of induction, also in a freer sense, the deduction is described as a process of transition from the general, universal, to the private, separate, truth.
