We can only know that which we experience. As we start to communicate with others, we can learn from their experiences as well, and eventually we arrive at some body of knowledge that we - each individual - consider true. This truth changes over time, as we gain more knowledge, and in some cases purge items when we find they are not true.
How and why we trust others' accounts of their experiences is something we each must arrive at individually - which is why no two people will react the same to what they are presented with. But there will still be a body of belief that seems to be pretty consistent within a population. I like to call the total of that body 'consensual reality'. It, too, changes with time. As a matter of fact, it is the job of advertisers to change it, in favour of their patrons.
In the end, we each are the center of our own individual universe - and no two universes are the same. There are large congruencies, of course, but they can never constitute a body of Truth, since we cannot know that everyone must include them in their universe. |
