## What happens

## Themes in this chapter

## Key lines

> That we uniformly judge improperly when we assent to what we do not clearly perceive, although our judgment may chance to be true; and that it is frequently our memory which deceives us by leading us to believe that certain things were formerly sufficiently understood by us.

We always judge wrongly when we agree to something we don't clearly see, even if it happens to be true; our memory often tricks us into thinking we once fully understood things we didn't.

_Descartes argues that assent without clear perception is inherently flawed, and memory is a common source of this error._
