Would this be cheating in LD Debate?

Given I have found no philosophical theory that fits my own ideas, can I create my own to use as a standard while debating?

I mean, I would never specify where I got the theory from, but given it is a philosophical thought process I do not see how it could be discredited just because of who created it.

It wouldn’t be “cheating,” persay, as long as the other side doesn’t ask for your source. But then again, I’ve only done pufo, so I may not be correct.
