@Ding an Sich,
You say science does not use causations but functions. Could you elaborate or provide an example?
There is inductive and deductive reasoning.
Inductive is drawing general conclusions from specific observations.
This is pretty close to the scientific method.
Deductive reasoning is lining up premises in an argument to arrive at a valid conclusion.
Even using deductive reasoning requires the use on inductive reasoning.
For example, you can deduce using valid premises that all people die. This is still based on inductive reasoning since you have to observe specific examples to draw that general conclusion. It's a valid conclusion and it used inductive reasoning as well as deductive reasoning.
My point there is that using inductive reasoning, you specifically observe the effect of a certain cause.
Even if you use deductive reasoning, you still have inductive reasoning underneath.
As for the gunshot thing, good clarification.
Point being, the cause of death would be more or less a chain reaction of cause and effect.
Gun is shot
Bullet strikes body
Bullet does damage to vital functions
vital function(s) cease
death
Science tells us the "Cause of Death" would be bleeding out or a punctured lung, etc. There you have it, death was caused by an effect.
What would the scientific function of that death look like?
