As is their personal opinion on the matter, since it's a subjective thing. The difference is that they have enough power to impose their opinion on other people.
Will you answer the question I've already posed twice:
Since you're referring to the use of the term in 1856, are you arguing that we should apply 1856 ideas of what constitutes reasonable behaviour to everyone today?
You're arguing that it's wholly objective and you're arguing that the 1856 legal opinion defines it, so why would you not apply 1856 ideas of what constitutes reasonable behaviour to everyone today?
And why choose 1856 England as the sole arbiter of what is reasonable? Why not 1356 England? Or 500BC Sparta? Or any other time and place in which "reasonable person" would have a different meaning?
If you bothered to read the judgment you'd know the answer to that.
You can claim things which ordinarily regulate the conduct of human affairs, things someone would do ordinarily, or doing something, which a prudent and reasonable man would not do has somehow changed its meaning in the last 150+ years but it's not.
The reason you wouldn't apply 1856 ideas of what constitutes reasonable behaviour to everyone today is because 1856 ideas of what constitutes reasonable is not what people would consider reasonable in 2023, you know what with the two times being separated by more than 150 years. Look i get it, you've got it into you head that 1856 England is the sole arbiter of what is reasonable and you've completely brushed over the fact that it says "which ordinarily regulate the conduct of human affairs", you know the fact that what ordinarily regulated the conduct of human affairs in 1856 of even 500BC Sparta is not what ordinarily regulates the conduct of human affairs in the UK in 2023.
However in doing so you're choosing a very strange hill to die on because you're totally ignoring the fact that things "which ordinarily regulate the conduct of human affairs" changes, just like society changes. That reasonableness is not a fixed standard, that it changes depending on the time, the place, and even the circumstances. It changes because what was reasonable in 1853 may not be what is reasonable in 2023. (and before you say it no that's not subjective, it's objective. Just like saying the Athlon 64 was the best CPU was an objective thing to say in 2003 but it's not in 2023)
Thanks for proving the point that the definition of a reasonable person changes depending on circumstance, much appreciated homeboy
No one said it didn't. Just because something changes depending on circumstances does not mean it's not objective, what's reasonable in one circumstance maybe different from what's reasonable in another but it doesn't somehow magically change what's reasonable.
Nice of you to admit that you were wrong on the whole objective/subjective thing though, oh wait...
Also, homeboy, you for real?
