"By what criterion... can we distinguish among the numberless effects, that are also causes, and among the causes that may, for aught we can know, be also effects, - how can we distinguish which are the means and which are the ends?"

This quote by Chauncey Wright is asking how we can compare causes and effects, and between means and ends. He is suggesting that it is tough to figure out which is which, as numerous results can likewise be causes, and many causes can likewise be effects. He is questioning how we can determine which is which, and what criteria we can use to make this distinction. This quote highlights the intricacy of domino effect relationships, and the problem of identifying which is which. It likewise suggests that we need to take care when making presumptions about cause and effect relationships, as they might not always be as precise as we believe. Ultimately, this quote motivates us to think critically and carefully when making choices and drawing conclusions about domino effect relationships.
