The fourth rule is tension. We cannot just pull all the virtues from the fifth dimension into our four of time and space. In practice, the virtues compete with one another. I might like to be punctual, but I should also be patient. I might wish to be a person of integrity, but sometimes I should compromise. We might value skepticism, yet we have faith. Love is blind, but it takes discernment to know what not to see. That leads us to the fifth rule: combinability. People can bring together virtues in creative ways and sometimes create new ones.
