how would you know the reason you came up with to explain something is actually right

"Things" happen and we assign a reason. To the religious, if they can not identify a reason, it must be "God's will."

It would be better to say " cause " instead of reason.
Reason implies Gods reason and that doesn't necessarily mean it's about you.

I think this was Einstein’s last revelation, I mean Marty Einstein my deceased friend from my old catholic school.The Academy of the Holy Morons in Queens NY.

Causality exists, so in that sense I agree, but people generally mean there's some predefined meaning or agency in how the universe unfolds, and I see no evidence to support that.

Great question brother. A lot of feedback.

I think nothing happens without a cause. We add the reasons after the fact to help give it meaning... which we legitimately need, and benefit from.

By supernatural design- no.
By natural consequence - yes.

The statement needs modification:
'There is nothing that happens without a cause.'

Again, that depends on your definition of "reason." When a program came on in which a clip of Ronald Reagan's 1980 campaign speech was played, for example, in which he asked me if I was doing better than I was four years previously, I was spinning my wheels in Louisville KY, working a dead-end grunt job with one useless masters degree under my belt and almost done with another. I had been applying for teaching jobs in the US to no avail and at the moment I heard Reagan ask me that, I was drunk and his question pissed me off. I threw a chair at the TV and broke it (last one I ever owned). When I sobered up, I decided to expand my job search overseas and vowed to take the first job I was offered.

As it turned out, that job was in South Korea. It could just as well have been in Saudi Arabia, Malaysia, Thailand, Japan, Colombia, or any number of other places I sent applications to. But that job turned my life around. It began a rewarding teaching career, and I ended up meeting the woman who would become my wife. We married and became a "teaching couple" and saw most of Asia and the Middle East during our careers.

Did it happen for a reason? Yes, in the respect that I happened to be watching a TV program that pissed me off enough that it goaded me into action. No, in the respect that I took the first job I was offered--that it happened to be in Korea was just random chaos. Further random chaos was that ten years after our stint in Asia, my died of cancer, with no history of cancer in her family (other than Uncle Bob, who smoked himself to death).

Sure, everything happens for a reason. It isn't a self-aware reason or a reason with intent--but mindless cause and effect.

Oh brother... Sometimes i think so for ( ME ). Then I think about the bad things that happen to people. Why would there be a reason for all that fire distroying homes in California. And this line of thinking going on and on. Given into reason means something is controlling our lives. Who knows. I can't say that there is an all powerful something controlling each and every one of us.

Maybe I am a fatalist

Everything that happens, happened.

everything happens for a reason.

That has been my theory of life. My daughter's three month premature birth was excrutiating. She fit in the palm of my hand literally. Watching her fight for life in an glass enclosed isolette in Albany Medical Center was tough on me and my ex. When she was released from ICU she came home on a bradycardia and apnea monitor. Watching her turn one years old at a tiny 10 lbs we had hopes she would be able to sit and do the things a "normal" baby would. I asked the pediatric specialist if she had cerebral palsy and he confirmed her diagnosis. I believe everything happened for a reason.

1. I only lived near Albany, NY for 2 years. It was one of the best hospitals with an ICU ward in the country.

2. We moved to Burlington, VT when my ex was transferred. Burlington,VT had Bernie Sanders as mayor and had one of the most progressive infant development programs in the country.

3. Three years later my ex accepted a transfer to Nashua, NH without checking in with me. Angry and worried how my daughter was being taken away from the wonderful friends and services we had received in VT I searched for the best school system near Nashua, NH. That was Merrimack, NH where I live to this very day. Becky is relatively happy and healthy at 34.

Yes things happen for a reason.

Yes, everything happens for a reason. And that reason is physics and/or psychology. There is no "cosmic plan".

I have to disagree. What reason is there behind earthquakes, tsunamis, famine, plague, etc.
