"Wretched creatures that we are! what resource for us amidst the innumerable ills of life, did not religion suggest some methods of atonement, and appease those terrors, with which we are incessantly agitated and tormented?"
From Dialogues Concerning Natural Religion by David Hume
About the second sentence structure, I have some questions.
First, why is the first letter of what (the starting word of the second sentence) not capital? As far as I know, exclamation mark serves the same syntactic function as period, so it should be "What" rather than "what", I guess.
Second, more confusing one, what is the status or meaning or function of the phrase "what resource for us amidst the innumerable ills of life," in the sentence? I think "religion" should be the subject, and "did not suggest"(inversion form) the verb phrase. I do not understand what the phrase is doing exactly. Please enlighten me with the pre-inverted sentence.
I appreciate your help.
