Causes

Every action is the result of a complex web of preceding events. Scientists and philosophers often look at causes through different lenses to understand this complexity:

: A proximate cause is the immediate trigger—for example, a match lighting a fire. The ultimate cause is the deeper reason—why the oxygen, fuel, and heat were all in that place at that time.

: A necessary cause must be present for an effect to occur (you need oxygen for fire), while a sufficient cause is enough on its own to produce the effect (a lightning strike is enough to start a forest fire). causes
