The word incredulous is usually used to describe a person's unwillingness/inability to believe. But I would also like to use it to describe an idea's inability to be believed. For example, instead of saying
I am unable accept this idea, not because of its technicality or abstraction, but rather my incredulity towards this idea.
I would like to say
I am unable accept this idea, not because of its technicality or abstraction, but rather its incredulity.
I know the word "unbelievability" exists, but I like the hyperbolic feel of "incredulity" more. To my ears, this sentence does not sound bad at all. Has anyone heard this usage before? Are there other natural ways of phrasing my sentence, i.e. other words that could be used that keep the sentence's meaning/tone?
