Argument from CAUSE TO EFFECT

Causal argumentation claims the existence of a causal link.
Argumentation from effect to cause, or argumentation by the consequences, assumes the existence of a causal link and concludes from an effect to a cause.

Argumentation from cause to effect assumes the existence of a causal law (a cause-effect relationship). The actual occurrence of the cause is materialized by the necessary occurrence of the effect. Argument:

There is a state of affairs c. This state of affairs c falls into the category of facts C.
Cause- Effect Rule: There is a known causal law linking state of affairs C to state of affairs E.
Conclusion: C will / must have an effect e, of type E.

The argumentation from cause allows prediction:

This bridge is made of metal.
When heated, this metal expands by a certain coefficient.
In summer the bridge will expand by such and such amount.

The argumentation from cause to effect can be refuted by showing that the causal relation it presupposes is poorly constructed, see Causal argument

Pragmatic argument

This preceding argument from cause to effect can be supplemented by a pragmatic argument.
Step (3) of a pragmatic argument consists in an argument from a cause to an (hypothetical) effect, an evaluation of this effect, followed by step (4) consisting in an argument from this effect to a cause:

Such dilatation can have dangerous consequences: Expansion can twist metal.

Precautions must therefore be taken:

Adequate expansion space must be provided for the bridge deck.

Argument from the existence of a motive for action to the action proper
The argument from motive to action mirrors the argument from cause to effect:

He had the desire and the ability to do it, he found the opportunity: so, he did it.
