[The One and Only...]

Many secondary sources that I read take direct quotations from the primary texts.

Any affirmation of doubt must be universal in order for it to be meaningful. If truth is not universal, then there is no truth in any traditional sense of the word - which creates a pardoxical stance, since an affirmation of the lack of truth is a truth itself.

If one is to be skeptical of skepticism, we enter the realm of logical paradoxes. How can I know that there are no univeral truths when I am skeptical of that very knowledge?
