Document Summary

Reasoning about alternatives and necessary and sufficient conditions pt. But causal claims do not need to use the word cause. ". Sometimes, a causal claim states a necessary causal condition: Watering a lawn will make it grow. Sometimes, it states a sufficient causal condition: We can avoid this ambiguity by reformulating the claim using a conditional: A lawn will grow only if you water it. If a thing drowns, then it will die. That means that all healthy lawns have water. It does not mean that all watered lawns are healthy. Suppose that drowning is enough to kill a person. That means that all drowned people die. It does not mean that all dead people drowned. Reasoning with causal claims as premises is just reasoning about necessary and sufficient conditions. If billy takes a tylenol, his fever will fall. Billy just took a tylenol, so his fever will fall.
