Argument from Conscience

[TheRealJoeFish]

Your sentence can be reworded without "it."  Consider:

Not following A's conscience is immoral.

I believe you may agree that that is equivalent to your sentence: "it is immoral for me to not follow A's conscience."

The word "it" in your sentence serves a grammatical function, rather than referring to something not otherwise mentioned in the sentence.  "It" refers to the state of affairs mentioned later in the sentence.



Overall, I rather like your post.

Ah, thank you.  I meant the second it (the one I've bolded/underlined here):

...
5) Individual consciences cannot be added unless each person relies on their own conscience to feel morally obliged to the group. (I think this means A's conscience cannot "oblige" B unless B'a conscience already says "it is immoral for me to not follow A's conscience.) Thus it is functionally equivalent to individual consience as a source. (I admit, I do not know what this means, because I don't understand what "it" refers to.)

What I mean to say is, I don't understand the second sentence in the OP paragraph 5.  Though what you're saying is important; I certainly haven't helped things when I complain about use of pronouns clouding meaning and then use that same pronoun in a grammatical, rather than substantive, way in my analysis of the preceding sentence.
