The single truth which is accessible to us is that while there is a single truth – we may call it ‘reality’, if you want, we’ll never know it in its entirety.
We may get ever closer to getting there but we will never arrive.

The corollary – which is an integral part of the kernel truth, being that the effort to get closer to that single truth can be exerted only as a collective endeavor. Any other approach will, sooner rather than later, end up in a cul-de-sac.

The sooner we agree about this ‘kernel’ truth, the more peaceful the journey to never get there will become.
