Believe it or not Blue, we are not disagreeing much on these points, but rather issues of use of language, particularly of words like “directly” which have one meaning in moral theology and potentially another in wider contexts, and a word like “contraception” which may be used with physical or moral meaning, and this creates smoke where there is less fire than might appear. Though I agree I have not been as consistent as I ought wrt PODE which I will aim to remedy in due course.
…Therefore if people can in unusual circumstances choose to contracept without “directly intending” to contracept…then people can…
It is a given that people may (licitly) knowingly choose an act with contraceptive effect, and in doing so the contraceptive effect need not be in the Intention font (ie. an intended end, or an intended means), nor is the moral object ‘contraception’. For example, in the case of rape victims, the administration of a spermicide (hospital) has the good moral object of interrupting a rape - to end the injustice. It is moral to interrupt a rape under the positive precept of “Love of neighbour”. The contraceptive effect is in the 3rd font, and is therefore indirect. Also in the 3rd font is the good effect of stopping an act of physical, emotional and mental harm. For completeness, I believe that abortifacients or subsequent (direct) abortion cannot be used. Killing a child does not interrupt a rape, and to act against the child is intrinsically evil.
in principle, surely [one may] choose to kill without “directly intending” to kill…
I think we have some uncertainty in the meaning of “directly…” and “indirectly…”. Certainly, indirect killing need not morally be morally evil.
In self-defence, every just act of self-defence causing death is an instance of a double effect. The good effect - saving one’s own life, the bad effect, the death of another. The balance is judged good, as preserving an innocent outweighs the loss of the one who is not (for he is guilty of unjust attack). So morality is determined by the other 2 fonts.
NB: Aquinas did not
explicitly analyse in terms of the 3 fonts, so reading him may not directly map onto how we analyse acts today by way of the 3 fonts.
It is permissible to intend harm in the means (and death is a form of harm), though never as an end, and only in service of a greater good in the end.
Such harm against an aggressor is not morally evil (though may still be called ‘bad’.)
In self-defence, the harm is in the (intended) means, it is not an end, nor is it the moral object. We may weigh the harm in the intended means against the good intentions - both together determine the morality of the Intention font. This is analogous to the physician choosing the “bad” of amputation. He may morally choose that “bad means” because it is outweighed by the good in the intended end. He may not morally choose “amputation” to achieve some minor health benefit.
Regarding “directly intended” - I think this is the proper usage: That which is “directly intended” is the moral object (the end in terms of morality of the chosen act itself). In self-defence, the act itself is killing a person, but he is an aggressor, hence the moral object of that is (not killing an innocent but) defence of innocent life. When we say something is “directly intended” - we refer to an object - which must be good, or evil.
The expression (in our context) “directly intended killing of an aggressor” needs some unpacking. It’s right to say it does not arise in genuine self-defence. It would refer to an act where *the moral object *is killing the one who is the aggressor. This would suggest choosing an act to produce death as an end. Such an act is evidently immoral.
…and people can, in principle, choose adultery without directly intending to adulter.
Do you say “in principle” because at present, you cannot conceive of how such a knowing choice could be moral, or do you rely on a meaning of “adultery” that excises the moral element [despite a knowing choice]? Or are you referring to an “objective adultery”, where the choice was made without knowledge? Perhaps all this strays too far from topic.]
