Another common type of reasoning is the search for causes and results. We want to know whether cigarettes really do cause lung cancer, what causes malnutrition, the decay of teeth. We are equally interested in effects: what is the effect of sulphur or lead in the atmosphere, of staying up late on the night before an examination.
Causal reasoning may go from cause to effect or from effect to cause. Either way, we reason from what we know to what we want to find out. Sometimes we reason from an effect to a cause and then on to another effect. Thus, if we reason that because the lights have gone out, the refrigerator won’t work, we first relate the effect (lights out) to the cause (power off) and then relate that cause to another effect (refrigerator not working). This kind of reasoning is called, in short, effect to effect. It is quite common reasoning through an extensive chain of causal relations. When the lights go out we might reason in the following causal chain: lights out – power off – refrigerator not working – temperature will rise – milk will sour. In other words, we diagnose a succession of effects from the power failure, each becoming the cause of the next.
Causes are classified as necessary, sufficient, or contributory. A necessary cause is one which must be present for the effect to occur, as combustion is necessary to drive a gasoline engine. A sufficient cause is one that can produce an effect unaided (as an empty gas tank is enough to keep a car from starting), though there may be more than one sufficient cause. A contributory cause is one which helps to produce an effect but cannot do so by itself, as running through a red light may help cause an accident, though other factors must also be present.
