79. One must therefore reject the thesis, characteristic of teleological and proportionalist theories, which holds that it is impossible to qualify as morally evil according to its species — its “object” — the deliberate choice of certain kinds of behaviour or specific acts, apart from a consideration of the intention for which the choice is made or the totality of the foreseeable consequences of that act for all persons concerned. (Veritatis Splendor)
I’m trying to take this through a step by step analysis based on what the church teaches.
1750 The morality of human acts depends on:
- the object chosen;
- the end in view or the intention;
- the circumstances of the action. (Catechism)
If the object is not intrinsically evil then the morality of an act depends on the intention. We should all at least be able to agree that the intent of the person who throws the switch is to save five lives, and the intent is therefore moral, but if the intent is moral and the object is not immoral, on what basis do we assert that the act is immoral?
