Faunus I would say it would probably be better to view that as something like:
The evidence of the senses is never 'wrong' but the opinions we draw from the evidence certainly can be. in this case there is some evidence and some argument that the universe is finite (what you are referring to) set against other evidence that the universe has no end (every time we expand the reach of our observation we find more).
This is the constant question in lots of areas - where the evidence conflicts we have to entertain multiple possibilities or wait before attaching ourselves to a single opinion. But the one conclusion to avoid above all is that the senses are ultimately untrustworthy and that we therefore have no capacity to be confident of anything. If you fall to that level you will walk off the precipice and your life will be unsustainable.
