What are Universals?

I now write on what I believe to be the most defective point to the philosophical position of the Biblical skeptic.  This is certainly not original with me; yea, it has been consistently promoted throughout the 20th Century where those putting forth the idea pointed rearwards to centuries prior and claimed to have read others, like Blaise Pascal, promote the very concept.  Well, Pascal himself wrote in regards to the idea, "In what I am writing, let no one think I am saying anything new." That this point has not been disproven to this day--the same line of reasoning, the same clear idea, the same consistent thought--speaks to the power and simplicity to the argument itself.
