What we do know is that somehow, very quickly, they've (the babies) acquired this ability to perceive number and divorce it from the sensory information.

As a result of our experiments, we conclude that the babies are showing an internal representation of 'two-ness' or 'three-ness' that is separate from sensory modalities and, thus, reflects an abstract internal process. These results support the idea that there is a shared system between preverbal infants and nonverbal animals for representing numbers.

I watch and I cry. I feel so bad. We can't get them out of there, those little babies with empty bottles.

The only thing more unthinkable than leaving was staying; the only thing more impossible than staying was leaving. I didn't want to destroy anything or anybody. I just wanted to slip quietly out the back door, without causing any fuss or consequences, and then not stop running until I reached Greenland.

These wretched babies don't come until they are ready.
