Fact & Truth x Belief & Assumptions - What Are The Differences?

[CARDOZZO]

I was contemplating this issue. We live in a mind full of bullshit, beauty, fantasies. 

What do you think?

How to make a distinction between Fact x Truth x Belief x Assumption?

How do you navigate reality? What do you use the most? 

[UnbornTao]

"Could it be said to be happening, or to have happened?" 

As a good starting point, I think that paying attention to the objective world helps - and also to the domain of objective feedback. 

[Joseph Maynor]

Fact -- a relative but concrete discernable truth.
Truth -- Absolute Truth and relative truth.  Relative truth includes but it not limited to facts. 
Belief -- holding a relative truth.
Assumptions -- beliefs that the small self is more or less conscious of.  Could be unconscious.
