Analogy

Analogy is a comparison or correspondence between two things (or two groups of things) because of a third element that they are considered to share.[1]

In logic, it is an inference or an argument from one particular to another particular, as opposed to deduction, induction, and abduction. It is also used of where at least one of the premises, or the conclusion, is general rather than particular in nature. It has the general form A is to B as C is to D.

In a broader sense, analogical reasoning is a cognitive process of transferring some information or meaning of a particular subject (the analog, or source) onto another (the target); and also the linguistic expression corresponding to such a process. The term analogy can also refer to the relation between the source and the target themselves, which is often (though not always) a similarity, as in the biological notion of analogy.

Ernest Rutherford's model of the atom (modified by Niels Bohr) made an analogy between the atom and the Solar System.

Analogy plays a significant role in human thought processes. It has been argued that analogy lies at "the core of cognition".[2]
