|
|

|
Term
|
Definition
A condition (state of
affairs, thing, process) that

|
|

|
Definition
A theory of causation
postulating that the cause of
an effect is found by noting
that X is the only factor always
present when Y (the problem
or the good effect) occurs;
therefore, X cause |
|
|
Term
|
Definition
A theory of causation
postulating that the cause of
