What Was it Like Before You Were Born?
Energy is Neither Created or Destroyed, And Death is Likely a Lot Like How it Was Before You Were Born
In other words, although no one knows what it is like to be dead (outside of those who have been brought back quickly and talk about white lights and such), but we all technically have experienced not being born yet.
Logically, using pure reason, we can assume that these two states are equivalent.
The argument for this is basic logic, we were not, then we are, then we are not again. Why would the states on either end be different?
Then from there we could question the point at which we “turn on” and become conscious (when we become us, when we get our, metaphorically speaking, “soul”).
The argument against the hypothesis that “before life is like after death” would be that our essence started upon our coming into the world (whatever that specific point is), that this essence and our existence added some specific property to our being, and that because of that property the span after death is different than the span before birth (that some impression of that property is retained after death).
There is really no way to know anything concrete about these metaphysical concepts, but we can confirm a single thing, and that is, to restate: “logically, after you die will be like before you were born”.
With that in mind, logic isn’t necessarily king (and neither is physics).
There is nothing about this that implies an essentialist or existentialist perspective, and I’d imagine it doesn’t conflict with many religious lines of thinking.
It is only simply a truism of physics and logic, to what degree it relates to the ethics of how we should act, or the mystic, spiritual, or metaphysics is anyone’s guess.
What Did You Experience Before You Were Alive?.
TIP: Consider, everything in the universe is immortal on some level. All energy in the closed system is as old as the system itself, if not older. That means that every quantum particle in our body has been here since the big bang and will remain here forever. Energy in a closed system cannot be created or destroyed, and blackholes can (probably) record information. We know all sorts of things about physics and logic, but metaphysics is a different story. What does it mean?! We don’t know. That is a question of metaphysics, metaphysics is the art of asking questions we can’t or don’t know the answer to for sure.
TIP: Existentialism is [very roughly speaking] the idea that existence precedes essence, that we can’t confirm if there is purpose, thus we must create our own purpose. This doesn’t mean we can’t believe there is purpose, or that purpose doesn’t come from a higher source (Pascal’s Wager and Kierkegaard’s Christian Existentialism are both Christian existentialist theories who pair religion and existentialism), it means that since we can’t know for sure we have to give our own lives meaning or have faith in something beyond our sensibility. The most difficult questions, the ones that test your faith or your lack of faith, are sometimes the best. They force you to face the realm of metaphysics (where philosophy and spirituality dwell).
