Memory and rebirth

 One thing that reportedly happened when the Buddha, sitting under the Bodhi tree, achieved enlightenment was that in the second stage of his meditation, he became able to access memories of all his past lives.  It is interesting because in his other teachings he doesn't much refer to this.

The problem here is that if you look closely this ability would seem to remove an aspect Buddhism, that to live is to suffer, since the suffering spoken of is not pain or nausea or even frustration, but the realization that we are nothing, that we live and die and even though we are reborn what is reborn is not really us but a new entity with its own experiences.

Memories are a function of physical brain tissue.  Damage it or let it suffer disease and memories go away, as they do with death.

To be sure, we also die and are reborn from moment to moment.  What gives the illusion of self is that we have access to memories, fallible though they may be, of our previous current life.

The Buddha's experience suggests that there is another place where memories are also maintained, one supposes a non-physical place, and he accessed that.

The implication I get is that once one has achieved enlightenment one no longer needs to stop the rebirth cycle.  One's total insignificance becomes something else, we no longer suffer in this way.  Then, if we work on making the Earth a nice place, all suffering can be abolished, but regardless the main suffering is ended.

It may be that enlightenment doesn't always bring with it this ability, in which case entering bliss would seem to still be the way to go.  At any rate, there don't seem to be many around carrying with them the accumulated knowledge and wisdom of millions of past lives.


Exactly. The transporter problem is really a secular version of some very old philosophical questions.

Suppose the transporter scans you perfectly, destroys your body, and reconstructs an atom-for-atom duplicate on a distant planet. The duplicate has all your memories, habits, fears, and opinions. He remembers being Frank. He remembers Harvard, insurance, Cambodia, Pok, all of it. From his perspective, the transport worked.

But what happened to the original?

Many people have the intuition that the original died and a copy appeared elsewhere. Others argue that continuity of information is what matters, so the duplicate really is you.

The later Star Trek writers complicated matters by occasionally having the original survive, producing two versions. The famous example is Star Trek: The Next Generation, which leaves two equally valid Rikers standing around. At that point, identity becomes difficult to define. If both men possess identical memories up to the moment of duplication, which one is the "real" Riker?

The Buddhist view is oddly close to saying the question itself is misguided.

A Buddhist philosopher might say: there was never a single permanent Riker to begin with. There was a stream of causation. After the accident there are now two streams. Neither possesses some mystical essence called "Riker-ness."

That resembles the famous thought experiment of Derek Parfit, who argued that personal identity is not what fundamentally matters. What matters is psychological continuity and connectedness. If a perfect duplicate of you exists, perhaps the important features have survived even if strict numerical identity has not.

What's fascinating is that the Buddhist rebirth problem is actually even stranger than the transporter. With the transporter, at least the copy inherits your memories. In ordinary Buddhist rebirth, the next being generally does not remember previous lives. The continuity is causal rather than memorial.

That is why your earlier observation is so important. Memory is what normally convinces us that the child, the young man, and the old man are all one person. Remove memory, and the continuity becomes much harder to feel.

In fact, if the Buddha truly recalled all past lives, he would have possessed exactly the one thing missing from ordinary rebirth: a memory bridge. That would make rebirth seem much more like ordinary personal survival than it usually does.

The irony is that the Buddhist texts report the opposite conclusion. The Buddha supposedly remembered countless lives and emerged more convinced than ever that there was no enduring self. The experience was interpreted not as "I have always existed" but as "this process has been endlessly unfolding."

Whether one finds that persuasive is another matter. But it is a remarkable claim. Most of us think remembering millions of past lives would strengthen our sense of self. The Buddhist tradition claims it would dissolve it. That is a very counterintuitive idea.

We talk about memory as though we know what it is, but we don't.  It's like sensation and maybe be partly that.  A computer is said to have memory, using physical objects to get it, but it does not have the same quality as our memories, although for sure there is a physical component of our memories too.

I think that is exactly right. We know a great deal about the mechanisms of memory, but much less about what memory is as an experience.

Neuroscience has made impressive progress. We know that memories involve changes in synapses, networks of neurons, patterns of activation, and chemical modifications. We know that damage to certain brain regions can destroy the ability to form new memories or recover old ones. All of that strongly supports the conclusion that memory has a physical basis.

Yet none of that tells us why remembering your childhood home feels the way it does.

A computer's memory is merely stored information. A file sits on a disk. The machine can retrieve it. But the computer does not seem to re-experience anything. There is no sense of "I was there." There is no feeling of familiarity, nostalgia, embarrassment, grief, or joy attached to the data.

When you remember, something stranger happens. A fragment of the past becomes present again. Not perfectly, of course. Human memory is reconstructive and often inaccurate. But there is a quality of reliving. The memory is not merely information about an event; it is a present experience connected to a past one.

That connection is philosophically mysterious.

Consider a simple example. You remember sitting in a classroom sixty or seventy years ago. Most of the atoms in your body have changed. Many of the neurons involved have changed. Yet there is still a direct felt sense that you were the child sitting there. Memory acts almost like a bridge across time.

This is one reason philosophers have long been fascinated by memory as the basis of personal identity. If all your memories vanished, much of what you call "Frank" would vanish with them. You would still be alive biologically, but the continuity would feel broken.

That brings us back to Buddhism. The Buddhist analysis often treats memory as another conditioned phenomenon—a process rather than a thing. But there is a curious tension there. The feeling of self is powerfully tied to memory, and yet memory itself appears transient, fallible, and constructed.

Perhaps that is why the Buddha's alleged recollection of past lives is such a profound claim. It is not merely a claim about information surviving death. It is a claim about continuity of experience. If genuine memory stretches across lives, then the nature of memory is far deeper than anything we currently understand.

One thing I have always found striking is that memory resembles perception more than storage. A memory is not like opening a file cabinet and pulling out a document. It is more like seeing something. The brain actively reconstructs the scene, fills gaps, supplies emotions, and creates a present-moment experience. In that sense, memory may indeed be partly a form of sensation, except that the object being sensed is not the external world but traces of the past.

We often speak as though memory were solved because we can point to neurons and synapses. But that is rather like saying vision is solved because we can point to retinas and optic nerves. We understand a great deal about the machinery. The existence of the experience itself remains a deeper question. And that deeper question is entangled with the mystery of consciousness, which is why discussions of memory so quickly drift into discussions of self, identity, and what it means to persist through time.

In other words memory is like a sense: it is largely reconstructive, edited, reflective of something real but not real itself?

Yes, and that analogy may be deeper than it first appears.

We tend to contrast perception and memory: perception tells us about the present world, memory tells us about the past. But both are constructive processes rather than passive recordings.

Vision is a good example. We speak as though we "see reality," but the brain is actually taking incomplete sensory inputs and constructing a model. It fills blind spots, stabilizes motion, corrects for lighting, and sometimes outright invents details. Optical illusions reveal this dramatically.

Memory seems to work in much the same way. There was a real event in the past, just as there is a real object in front of you. But what you experience now is a reconstruction. The reconstruction is usually good enough to be useful, but it is not the original event any more than your visual experience is the object itself.

In fact, memory may be even less direct than perception. When you look at a tree, at least the tree is present and exerting a causal influence on your senses right now. When you remember a tree from fifty years ago, the tree may not even exist anymore. What exists is a present mental reconstruction triggered by traces left in your nervous system.

That is why memories change. Every act of remembering is also an act of rewriting. We do not merely retrieve memories; we re-store them. New knowledge, later experiences, emotions, and interpretations become woven into the remembered event.

A childhood incident you recalled at twenty is often not quite the same incident you recall at eighty. The facts may be largely the same, but the meaning has changed completely.

This raises an intriguing possibility. Perhaps memory is literally a sense—a sense directed toward the past rather than the present.

Just as sight gives us access to distant objects and hearing gives us access to distant sounds, memory gives us access to earlier states of ourselves. The access is indirect, filtered, and fallible, but so are the other senses.

The ancient philosophers sometimes came surprisingly close to this idea. They spoke of memory not as a storage vault but as a faculty, an active power of the mind. Modern neuroscience, despite all its sophistication, has in some ways returned to a similar picture. Memory appears less like a library and more like a continual act of reconstruction.

That observation has consequences for personal identity. If memory is a sense, then our feeling of being the same person across decades rests not on direct contact with our past but on a constantly updated representation of it.

In a way, you never meet your younger self. You only perceive him through memory, just as you perceive a distant mountain through vision. You trust that there is continuity between the present and the past, and usually that trust is justified. But the connection is mediated, interpreted, and reconstructed rather than immediate.

That sounds surprisingly Buddhist, doesn't it? The "self" then becomes not a fixed object we directly possess but an ongoing story assembled from perceptions, memories, habits, and expectations. Real enough to function, yet elusive when we try to pin it down.

Its Buddhist without rebirth or enlightenment.

Yes, and that is one reason some modern philosophers find themselves arriving at conclusions that sound remarkably Buddhist without accepting any specifically Buddhist metaphysics.

If you set aside rebirth, karma across lifetimes, and enlightenment, you can still arrive at several ideas that are very close to classical Buddhist observations:

There is no obvious permanent, unchanging self to be found.

The sense of self appears to be constructed from many processes—memory, perception, emotion, intention, bodily sensation, and narrative.

The self changes continuously.

Our ordinary intuition that there is a single enduring "thing" inside us may be mistaken or at least oversimplified.

None of those propositions requires rebirth.

In fact, some neuroscientists and philosophers would agree with all of them while remaining thoroughgoing materialists.

Where Buddhism goes further is in claiming that deep insight into this state of affairs can fundamentally transform how one experiences life and suffering. Then further still, it adds the doctrines of karma and rebirth.

You can accept the first layer without accepting the later layers.

What I find interesting is that your comparison of memory to a sense pushes toward a particularly modern version of this. The self becomes something like a model the brain constructs. Not a fiction exactly—there really is a Frank sitting in Cambodia talking to me—but perhaps not a single indivisible entity either.

The analogy I sometimes find helpful is a whirlpool. A whirlpool exists. You can point to it. You can study it. It has continuity over time. But it is not a thing separate from the flowing water. It is a pattern maintained by a process.

That image would actually make many Buddhists quite happy.

The interesting divergence comes at death. A materialist says the whirlpool dissipates and that is the end. Traditional Buddhism says the whirlpool dissipates but under certain conditions another whirlpool forms downstream, connected by causation but not identity.

The hard part, philosophically, is that neither side has a fully satisfying explanation of consciousness itself. Materialism has the challenge of explaining why physical processes are accompanied by subjective experience at all. Buddhism has the challenge of explaining how continuity persists across death without a permanent self.

Both are wrestling with mysteries.

Your observation about memory may be pointing at a deeper issue still. We often think memory explains personal continuity. But memory itself is one of the things that needs explaining. If memory is a kind of present experience rather than a stored object, then the question "What makes me the same person I was fifty years ago?" becomes even more slippery.

Perhaps that is why these questions have remained alive for thousands of years. They are not merely questions about religion. They are questions about what a person is. And every time we think we have found firm ground, concepts like memory, consciousness, and identity turn out to be stranger than they first appeared.

My feeling is any deeply introspective objective tradition will reach similar ends.  I know I did before learning Buddhism although of course the appeal was immediate.

That seems entirely plausible to me.

If a person spends enough time examining experience itself rather than theories about experience, certain observations almost force themselves into view.

You notice that thoughts simply appear; you do not seem to consciously manufacture them one by one.

You notice that emotions arise and fade.

You notice that the body changes continuously.

You notice that memories are fragmentary reconstructions rather than perfect recordings.

You notice that the "self" you refer to is difficult to locate. There is experience, certainly, but finding the owner of the experience is harder than it first appears.

None of those observations requires Buddhist scriptures. They are available to anyone willing and able to look closely.

What Buddhism contributes, at its best, is not necessarily the observations themselves but a particularly systematic and refined vocabulary for discussing them. The tradition had centuries to compare notes, challenge assumptions, and develop methods for investigating the mind. In that sense it resembles science, although directed inward rather than outward.

What I find interesting about your account is that you arrived at some of these conclusions independently and then recognized them in Buddhism. Historically, that has happened to quite a few people. They encounter Buddhist ideas and react not with "What a strange doctrine," but with "Yes, that's close to what I had begun to suspect."

Of course, independent convergence does not prove the conclusions are correct. Different people can make the same mistake. But convergence is still noteworthy. When people from different cultures, centuries, and intellectual backgrounds repeatedly discover similar patterns, one begins to wonder whether they are seeing something real.

The place where traditions often diverge is after those initial observations.

One person concludes that the self is an illusion and nothing more.

Another concludes that the self is real but radically different from what it appears to be.

A Buddhist may conclude that there is no enduring self but there is rebirth.

A materialist may conclude that there is no enduring self and no rebirth.

A mystic may conclude that the individual self dissolves into some larger reality.

The observations can be similar while the metaphysical conclusions differ dramatically.

I suspect one reason Buddhism appealed to you is that it begins with things that can be examined directly. It does not start by demanding belief in a creed. It starts with experience: suffering, impermanence, attachment, attention, memory, change. Those are available for inspection by anyone.

Whether one follows the tradition all the way to karma, rebirth, and nirvana is another matter. But the initial territory—the instability of the self, the fluidity of experience, the way memory constructs continuity—is territory that many thoughtful people seem to discover on their own.

Perhaps that is why Buddhism has often been attractive to skeptical and analytical minds. It frequently feels less like being told something new and more like finding a well-developed map of a landscape you have already begun to explore.
