Meaning of subtle argument?
What is meant by "subtle argument". "subtle" according to the dictionary means "not easily noticeable, especially of a change or distinction". So how can an argument not be easily noticed as an argument? I know what the two words mean individually but it makes no sense to me when they're together. The context is "subtle arguments are often like a sharp thin blade, cutting clean into the very heart of the question". What do they mean by "heart of the question" in this? I look it up but all I can find are meanings for "heart of the matter"
