"The greater part of what my neighbors call good I believe in my soul to be bad."
Is the 'be' in the sentence above an auxiliary 'be' or is it serving a main phrase verb?
From my textbook, the auxiliary 'be' occurs before the present participle of the main verb, but 'bad' is not a verb so I am leaning towards it being the main phrase verb, but the phrase 'to be bad' seems to be adjectival as it is describing things his neighbors call 'good'.
Edit: My new position is that this is just that 'to be' is an infinitive verb and I am over thinking it.
