First you need to note there are many perspectives to what-is-reality from the crudest common-sense to the highest philosophical perspectives.
You are merely stuck in the common and conventional sense of reality. In these two perspectives, no normal person will doubt there is no common sense table at all. In these perspectives, there is a table for putting things on and avoid bumping into.
But to advance in knowledge one must be able to shift gears into the higher levels of knowledge.
Example, common sense tells us water, ice, steam, clouds are distinctly different to the uninformed. But for a physicist or chemist, these are all the same when they are turned to steam or all to ice, or looked when within a electron microscope.
Therefore if someone insist water, ice, steam, clouds are distinctly different, there is room for doubts to discover the higher truths that they are in fact the same from a different perspective.
There was once where physical objects down to the quarks are independently objective from the subject, but then the Wave Collapse Function proved the final object could be a wave or particle depending on the subject’s intervention.
Thus one of the greatest asset for one to doubt [a real independent permanent object table] is the opportunity to achieve higher advance knowledge that could optimize one’s well being and that of others.
The critical point here is to accept the table is real in one sense while at the same time, it is not real in another sense, i.e. accept p and not-p exists at the same time in different perspectives.
One ultimate is to recognize the self is real in one sense and at the same time an illusion in another sense in different perspectives.
This p and not-p will prevent one from clinging to a God to save the only real self [dogmatic belief] to eternal life where that God is accompanied by words and commands to kill and commit relentless evils upon non-believers.
Btw, you still have not demonstrate [against Russell’s doubts] to me there is a real independent and permanent objectively real table out there.
Note a can with 10 marbles is different from a can of 100 marbles.
A table has X number of atoms and electrons, and this number changes at every micro-second. Thus you cannot claim there is a permanent same objective table out there.
A more obvious would be an objective apple out there on a table.
That apple has X number of atoms and electrons.
At every nano-seconds, there could be atoms leaving the apple or added to it from the air.
With such nano-changes one cannot claim there is a permanently same apple.
In time that supposedly permanent objective apple out there would be a rotten apple with X minus 1-billion atoms and later becoming a mere pile of rubbish.
