The Hand That Knew First

The man on the screen was sorting blocks with his left hand, and his left hand was doing it wrong on purpose.

"Pause it," said Maya.

Soren paused it. The man's right hand had darted across the table to grab the left one, like it was stopping a stranger.

"He's fighting himself," said Maya.

"His left hand was doing the puzzle right," said Soren. "Then his right hand came over and messed it up. Or fixed it. I can't tell which one is him."

"They're both him."

"That's the part I don't get."

Maya leaned in until her nose was almost on the laptop. The narrator said the man had a surgery, years ago, that cut the bridge between the two halves of his brain. The seizures stopped. But something else happened that nobody expected.

"Play it," said Maya.

The scientist flashed a word on a screen, very fast, only on the left side. The man said he saw nothing. Then she asked him to draw what he saw, with his left hand, behind a curtain where he couldn't watch. His left hand drew a key.

"He said nothing," said Soren. "His mouth said nothing. His hand drew a key."

"So one half saw the key."

"And couldn't say it. Because the part that talks is the other half. And the bridge is cut, so the talking half never got the message."

Maya sat back. The oven ticked. The kitchen smelled like the first three minutes of cookies, when it is only butter and hope.

"Soren. Cover one eye."

"Why?"

"Just do it. Cover your left eye and read me the cereal box."

He did. He read it. Nothing strange happened. He took his hand away.

"That didn't prove anything," he said. "My bridge isn't cut. The two halves of my brain are talking the whole time. They just pass it across."

"Right." Maya tapped the table. "Right now there's a wire in your head, this exact second, sending the cereal box from one side to the other so fast you don't even feel it happen."

Soren stopped. He put the box down slowly.

"It's happening right now," he said.

"It's always happening. You just never get to notice it because it's never broken."

He reached for his notebook and drew two circles with a thick line between them. He stared at the line.

"Okay," he said. "Okay. But here's what's bothering me. When the man's left hand drew the key, did the silent half know it was drawing a key? Or did it just draw?"

"What do you mean."

"I mean is there somebody in there. In the quiet half. Watching the word, wanting the key, picking up the pencil. Or is it just a half doing half things."

Maya didn't answer right away. On the screen, frozen, the man was looking at his own left hand with an expression Maya recognized but couldn't name. Surprise. Like the hand belonged to a guest.

"The scientist asks him," Maya said. "Watch. She asks him why his hand drew that, and listen to what he says."

Soren pressed play. The scientist asked. The man looked at the key his own hand had drawn, and he smiled, and he said, with total confidence, "I guess I was thinking about my car."

Maya laughed out loud. Then she stopped laughing.

"He doesn't know," she said. "He's making it up."

"He's not lying," said Soren. "He believes it. The talking half didn't see the key, so when the hand drew one, the talking half just. Filled in a reason. A car has a key. Good enough."

"So the talking half makes up stories about what the rest of him does."

"And it's sure it's right." Soren's pencil had stopped moving. "It's always sure."

They sat with that. The oven ticked twice.

"Soren," Maya said, and her voice had gone careful. "Your talking half. The one explaining everything right now in your head. The one that says I did this because, I want this because."

"Don't."

"It's only one half."

"Maya."

"The other half is in there too. Right now. Behind the bridge. Seeing things, wanting things, and it doesn't get to talk. So you never hear it."

Soren put both hands flat on the table and looked at them like the man on the screen had. Left hand. Right hand.

"That's the worst thing you've ever said," he said. "That's amazing. Say it again."

"There might be somebody in there who never gets to use the mouth."

"Stop." He was grinning now, the scared kind. "But it's not true for us. Our bridge works. There's just one of us. The two halves are stitched together so tight that it all feels like one person."

"Does it," said Maya.

"What do you mean does it."

"You ever start moving toward the fridge before you decide you're hungry? You ever know an answer before you can say how? You ever raise your hand in class and your hand's already up and then your brain goes, oh, I guess I knew that?"

Soren's mouth opened.

"That's me in math," he said quietly. "My hand goes up. Then I figure out why."

"That's me always," said Maya. "I get the answer first. Then I find the reason walking backward. Everyone acts like I'm doing it wrong. Like the reason is supposed to come first."

"It doesn't, though."

"Not for me. The knowing comes first. The words come after, all out of breath, trying to catch up."

Soren looked at his drawing. Two circles. One thick line. The line that, in the man on the screen, had been cut, so that the knowing and the saying came apart and you could finally see the seam.

"There's a part of you that knows things before you do," he said. "And in most people it just whispers across the bridge and the talking part takes all the credit."

"And calls it me," said Maya.

The oven timer went off. Neither of them moved for it.

Soren reached out his right hand toward the laptop to play the next part. Halfway there his hand stopped on its own, hung in the air, fingers open, while the man on the screen waited frozen, smiling at the key he hadn't known he drew.

Soren watched his own hand hang there, not yet told what it was reaching for.
