Analogy is an important way of thinking.

A person sees something new, and thinks ‘what is it’?

Then he might think, ‘Ah, it’s like something I have seen before…’

So an analogy is a comparison between two things which we think are similar in some way.

We compare two things, or two systems, and think they have something important in common.

Definition from Analogy

An analogy is a comparison in which an idea or a thing is compared to another thing that is quite different from it. It aims at explaining that idea or thing by comparing it to something that is familiar. Metaphors and similes are tools used to draw an analogy. Therefore, analogy is more extensive and elaborate than either a simile or a metaphor. Consider the following example:

“The structure of an atom is like a solar system. The nucleus is the sun, and electrons are the planets revolving around their sun.”

Examples of Analogy:

  • Life is like a race. The one who keeps running wins the race, and the one who stops to catch a breath loses.
  • Just as a sword is the weapon of a warrior, a pen is the weapon of a writer.
  • How a doctor diagnoses diseases is like how a detective investigates crimes.
  • Just as a caterpillar comes out of its cocoon, so we must come out of our comfort zone.
  • You are as annoying as nails on a chalkboard.




  • One good analogy is worth three hours discussion. - Dudley Field Malone, American Politician
  • Prediction by analogy -creativity - is so pervasive we normally don’t notice it. - Jeff Hawkins
  • The greatest thing by far is to be a master of metaphor. - Aristotle
    • “But the greatest thing by far is to have a command of metaphor. This alone cannot be imparted by another; it is the mark of genius, for to make good metaphors implies an eye for resemblances.” ― Aristotle
