Evidence that demands a verdict

[Grace]

belief is an acceptance that a statement is true or that something exists.
"his belief in the value of hard work"

or trust, faith, or confidence in someone or something.
"a belief in democratic politics"

If we don't discuss our beliefs, if we only speak in echo chambers we will never grow, we will never learn, we will simply stagnate and die. A belief is not limited to religion, beliefs are 99% of everything discussed online, or are the basis of those discussions.

Personally, while some may think echo chambers are healthy, that some things should never be discussed outside of them, I see echo chambers as an illness, and they certainly characterize many illnesses of our day. Rather than going outside of the echo chamber to learn and grow, people more and more seek their own personal echo chamber and shut out the rest as if it doesn't have value, as if that which is outside the echo chamber is a thing to fear.

I will never seek the echo chamber, I will seek to learn and interact with those who hold different beliefs from me, which will cause me to grow in potentially beneficial ways. I see that as healthy. I would not be who I am today if I had stayed inside an echo chamber - and I am better for it.

In the end, to each his own.
