Double-aspect theory is a way of looking at something from two different points of view. It means looking at the same thing in two different ways or from two different perspectives. For example, a teacher might look at a student's report card from one angle – they are looking at the grades the student has, but from another angle – they can look at the progress the student has made since the last report card. Double-aspect theory helps us think about things in a more complete way and can help us understand more about situations.
