Ethics can only have regard to suffering indirectly, merely to show that what takes place merely to avoid suffering wrong is itself no infliction of wrong.

Context

“The pure doctrine of right is thus a chapter of ethics, and is directly related only to action, not to suffering; for only the former is the expression of will, and this alone is considered by ethics. Suffering is mere occurrence. Ethics can only have regard to suffering indirectly, merely to show that what takes place merely to avoid suffering wrong is itself no infliction of wrong. The working out of this chapter of ethics would contain the precise definition of the limits to which an individual may go in the assertion of the will already objectified in his body without denying the same will as it appears in another individual;” source
