However, you are asserting that actions are deliberately caused to achieve a particular end. That then rules out those adjectives used in the dictionary definition of “unreason”. Thus, you are giving the world of human actions an order and predictability that is not always true. We don’t have to think very hard to recall examples of human decision making that is chaotic, unreasonable, confused and/or disordered.
Good points. I think the difference here is between what we might call “right reason” versus the distinction between a deliberate act and randomness.
Human reason is not perfect - true. Just because a human being thinks of a goal, doesn’t mean that the action will achieve the goal.
So I think the statement “any action directed at an end” assumes that we can determine that the action was directed at the end that it achieved. It was something that was purposeful.
Your first sentence tells us that reason is required to establish an end. Therefore, when we see unreasonable ends, or irrational ends, or chaotic ends, according to you, there is reason behind them and not unreason.
This is an interesting point. If unreasonable, irrational and chaotic results are actually “ends”, then you could argue that every act has an end.
If that was the case, then reason would not be required since whatever action that took place anywhere would have some kind of end. This, however, would destroy the meaning of the words “end” or “goal” – as well as the words “purpose” or “by design”.
That doesn’t hold true in the observable world. Your archer, for example, might try to shoot an arrow into a target, but, not having allowed for the wind, shoots dead a stranger instead. He will be charged before a court with non-proper use of his reason and he daren’t plead intention, as your example suggests!!
First, he could be charged with something if he didn’t follow necessary precautions. If he set up his target in a heavily populated shopping area, he couldn’t claim that the killing of a person was totally unrelated to the end or goal he had in mind.
But let’s say it was wildly random, with no fault of his own …
The reason we look at intention is because we know the arrow could not have hit a person on its own. The fact that an “end” for the action was established beforehand (it was meant to hit the target) is actually the thing that will save this archer from going to jail.
We see it was a deliberate, purposeful act and not just a random shooting. It was intended to hit a target. We see the target, we see where he was standing, etc.
In this case, the arrow did not achieve the end it was directed at. So, our initial statement wouldn’t apply.
When an action has an end it has been established with a purpose
The end for this action was established before the act. It required the use of reason. The end for this act was that the arrow was supposed to hit the target.
So I think the problem you’ve raised is whether the arrow killing a person is an action directed to an end.
Was it the purpose of the arrow to kill a person?
I can see where this gets difficult.
The arrow itself doesn’t have a purpose of killing people or even of hitting targets, necessarily.
The question might be: “what kind of end or purpose can we determine from random acts”?
… this leads to the questions …
Are any actions truly random (or ultimately the product of unreason)? and … Is it possible for any action in the universe to not have an end or a goal?
If we could look at it from God’s perspective, every action has purpose, so there is nothing random. But from a human perspective, we make a distinction between deliberate and random actions.
Back to the OP.

I would add its possible Aquinas is only speaking of human actions (ST 1-II, Q90, A1), but its not clear that he is/
Another way to read this is like this:
“If an action is directed to an end, it must necessarily be done by reason”.
