# Use lenses to view the world¶

There's a lot of different ways of looking at things. Collect them, and switch between them to view the world. Use them to see different perspectives about the important things.

Different lenses can often be linked to different mental models. Building up an intuition for which lens to use at which time is possible. Be aware of the lens you're using

## Backlinks¶

- Be aware of the lens you're using
- Different ways of looking at things have different expectations. We should be aware of the lens we're currently using to view the world and we should be aware of what we're expecting to see. If only to mark the difference with reality. We should look with intent.

- A set-theory monoid and a category-theory monoid are the same thing
- The set theory definition and the category theory definition of monoids are different views over the same concept. Category theory defines a monoid as any category with a single object. Set theory defines a monoid as a set with an associative binary operation and a unit element.
