What is an observable truth?
In science, an observable truth is essentially that which can be perceived using the unaided senses. So that which you can see, touch, etc. not what you think is the truth.
Why is this important?
Well, the root of so many disagreements is based on independent views of the truth, better known as perspective. And a perspective is more closely associated with values than evidence or facts. So when you find yourself disagreeing with someone about what you or they think is the truth, you’re probably arguing more about perspective than the truth.
There probably is some truth buried within a disagreement, but it’s more of a blurred line than a solid point. Philosophers and scholars have been studying and discussing truth for centuries and there is still much disagreement as to what truth really is.
So the next time you find yourself disagreeing with someone about what you and they think the truth is, maybe just pause for a moment and reflect on the fact that so much of what you think to be the truth is just your perspective on the matter and not a fact backed by hard evidence. During your reflection, your opponent might seem a little confused at your lack of willingness to continue the argument, and you’ll have the satisfaction of knowing that you’re probably both wrong.
