"Faith" Is A Fine Invention Poem by Emily Dickinson

This is an anti religious poem. She is calling faith an 'invention' i.e. something made up by people - a technology. In particular, it is an invention used by 'Gentlemen' or the establishment support their version of the 'truth'. While religion may be a useful 'tool', if you actually want to find the truth of something, especially if its important, then science / actual observation is required.

faith is a tool much like a microscope...

I come back to thus one from time to time.faith is a spiritual protection but science is the physical proof the spiritual cannot deny

This one never gets old. In four lines she reduces faith to the need of people to have some control over their lives. Where as a microscope can reduce that prr

I like this poem, and while Emily Dickerson may have been stating this about all Faith, I interpret the word being in quotes to be referring to those who use Faith as a tool to manipulate their community and the people around them… (ie. Televangelists or those who preach the prosperity gospel)

This a thought that gets straight to the point via the power of the microscope that requires no faith.

Let's just beat it to death. Good grief, people!
