## AI overview

An introductory tutorial defines category theory and explains its purpose as a unified language for organizing mathematical structures across disciplines. It introduces examples and prepares readers for the formal definition of categories.

## Source excerpt

For a list of all the posts on Category Theory, see the Main Content page. It is time for us to formally define what a category is, to see a wealth of examples. In our next post we'll see how the definitions laid out here translate to programming constructs. As we've said in our soft motivational post on categories, the point of category theory is to organize mathematical structures across various disciplines into a unified language.
