Game of Perspectives

The game perspectives is based on the following principles:
1. A belief is merely an idea treated by its bearer as truth.
2. Most ideas have a perspective bias - influenced by ones currently held beliefs.
3. If you look at a cube from a certain perspective, it's a square. 
4. Reality is subjective, as eloquently explained here.

First, you have to acknowledge your current beliefs.
Then, you let them go.
Next, you think about various ways other people might view the subject matter.
Finally, you pick the one you like best.
