[tacticalogic]

All thinking takes place in this entity, which is perfectly undetectable by sense perception.

The "thinking" is not the "knowlege". One is process, the other is result. The result is what has been categorized, not the process. You may use whatever process you wish. Which realm the result falls into will depend on how it is expressed and communicated. For it to fall into the realm of scientific knowlege, it should be expressed and communicated empirically.

For it [thinking?] to fall into the realm of scientific knowlege, it should be expressed and communicated empirically.

What do you mean by the word "empirically?"

Just askin'.
