Saurabh reacted to
Grames in Hume's Is-Ought problem
When Hume writes his conclusion:
for what seems altogether inconceivable, how this new relation can be a deduction from others, which are entirely different from it."
"new relation" refers to the 'ought or ought not', "others" refers to 'is or is not'. Rewriting this thought as a stand-alone sentence gives:
It is altogether inconceivable that "ought or ought not" can be deduced from "is or is not", because ought is entirely different from is.
