Expression 4 and Expression 9
Expression 4 and Expression 9 compare two ways of operating in the world. Here is how the styles meet, in work and in the ordinary run of a day.
How Expression 4 and 9 get along
4's building is practical; 9's building is meaningful. 4's behaviour is grounded, systematic, and concerned with what works. 9's is expansive, principled, and concerned with what matters. The disconnect shows up when 4's question is "how?" and 9's answer is always "why?", both valid questions, pointed at completely different problems.
The two on their own
