This group believed that art symbolized many things of the real world (such as animals) and the supernatural world. When they performed their rituals they would use different ceremonial masks depending on what they wanted to represent; in the majority it were ancestral experiences. They used the Crooked Beak mask when they wanted to express experiences of spirits that have faced the Bakhbakwalanooksiwey, an upper cannibal spirit and they would dance using the masks.

Answer:

He used philosophy of Legalism which gave absolute power to the king and encouraged strict laws and harsh punishments.

Explanation:

Philosophy of Legalism is based on the assumption that Human beings are inherently selfish and will always do things to serve their own interest.

This is why supporters of legalism tend to support giving absolute power to the Central government (Kings and his trusted people;.)
