You Can't See My Red: The Strange Problem of Other Minds

Every time you feel understood by another person, something philosophically extraordinary — and slightly miraculous — has occurred.

The Idea

There is a peculiar loneliness built into being conscious. Your experience — the exact quality of seeing red, the texture of grief, the particular way silence feels at 3am — is, strictly speaking, inaccessible to anyone else. This is the starting point for what phenomenologists call the problem of intersubjectivity: how do separate streams of first-person experience manage to constitute a shared world? Husserl, who founded phenomenology in the early twentieth century, noticed that we don't actually experience other people as objects we merely observe from the outside. Something stranger happens. When you watch a friend wince in pain, you don't first register a facial muscle contraction and then infer suffering — you apprehend it directly, as if across a gap that shouldn't be crossable. He called this 'analogical apperception': our own bodily experience gives us a living template that we spontaneously project onto the bodies of others. Merleau-Ponty pushed this further. For him, intersubjectivity isn't primarily a cognitive problem to be solved — it's something the body enacts before thought kicks in. Infants mirror expressions within hours of birth. We finish each other's sentences. We yawn contagiously. The self, on this view, was never sealed shut in the first place. It is constituted in relation, porous and social all the way down. The mystery isn't how we reach each other. It's why we ever thought we were entirely separate.

In the World

In the 1990s, a neuroscience team in Parma made an accidental discovery that reframed this debate. While studying a macaque monkey's motor neurons, they noticed that the same cells fired both when the monkey reached for a peanut and when it simply watched a researcher pick one up. The neurons couldn't distinguish between doing and witnessing. These became known as mirror neurons, and when analogous systems were identified in humans, phenomenologists took notice. Vittorio Gallese, one of the Parma researchers, began collaborating directly with philosophers. He argued that what Merleau-Ponty described as the body's pre-reflective grasp of others had now found a neural correlate. We don't simulate other minds by running cold calculations — we resonate with them, motorically and viscerally, before any conscious reasoning begins. This has implications that extend beyond the neuroscience lab. Therapists working in trauma began to understand why bearing witness to another person's pain is itself an embodied act — why sitting with someone in distress is genuinely taxing, not because you're being dramatic, but because your nervous system is partly living their experience alongside them. The cliché that empathy is 'putting yourself in someone else's shoes' turns out to be less metaphorical than we thought. Something close to that transposition may be happening in your body, right now, whenever someone you love is afraid.

Why It Matters

If the self is porous rather than sealed, this changes how you might approach a mundane Monday. The irritability you picked up from a colleague at the start of the day, the unexpected lift from a stranger's smile on the commute — these aren't just social noise. They are, on this account, evidence of your fundamental entanglement with other minds. It also reframes what presence actually means. Mindfulness is often taught as a turning-inward: attend to your breath, your body, your thoughts. Intersubjectivity suggests that attending outward — genuinely attending to another person's face, posture, tone — is equally a practice of awareness. You are not departing from your experience when you attend carefully to someone else's. You are deepening it. And it quietly dismantles the idea that understanding another person is mainly an intellectual project. You don't understand your partner by accumulating data points about them. You understand them by being with them, in the bodily, temporal, unglamorous sense of that word. Comprehension, here, is less an achievement of the mind than a willingness of the whole person.

A Question to Ponder

When was the last time you felt genuinely understood by someone — and what, exactly, do you think happened between you in that moment?
