In other words, the ground taken is this: sense-awareness is an awareness of something.

What then is the general character of that something of which we are aware?
We do not ask about the percipient or about the process, but about the perceived.

I emphasise this point because discussions on the philosophy of science are usually extremely metaphysical--in my opinion, to the great detriment of the subject.
The recourse to metaphysics is like throwing a match into the powder magazine.

It blows up the whole arena.

This is exactly what scientific philosophers do when they are driven into a corner and convicted of incoherence.
