Philosophy 148. Round two.

From A Concise Introduction to Logic 10th ed:

"...When the word 'cause' is used in ordinary English, however, it is seriously affected by ambiguity...To clear up this ambiguity affecting the meaning of 'cause,' adopting the language of sufficient and necessary conditions is useful. When we say that electrocution is a cause of death, we mean 'cause' in the sense of sufficient condition. Electrocution is sufficient to produce death, but there are other methods equally effective, such as poisoning, drowning, and shooting."
