Alex;
I know of 3 different types of reality:
1) Physical Reality - eg: Jack Russel dogs exist because they can be measured, weighed and charaterised, repeatedly by anyone (not just me);
2) Reality in one's own mind - eg: "I imagined that giant Jack Russels exist then I observed a big mountain that must've been caused by a giant Jack Russel. So therefore, they're real (but nobody else knows that, except me). A better example without the irony may be feeling hungry - hunger is real, folks but when I'm hungry I'm the only one who knows it;
3) Reality by Concensus - what politicians practise - eg: "Giant Jack Russels exist because me, my mate and everyone else agrees that they do - so they are real".
But Gravity (or the 'force of attraction) falls well and truly into (1) above. ?? Illusion ?? - Only if one's mind is in either of the other two realities !!
Cheers
