WHICH ARE THE DIFFERENCES BETWEEN HUMAN BEINGS AND ANIMALS?

1. Generative computation

Humans can generate a practically limitless variety of words and concepts. We do so through two modes of operation recursive and combinatorial. The recursive operation allows us to apply a learned rule to create new expressions. In combinatorial operations, we mix different learned elements to create a new concept.

2. Promiscuous combination of ideas

"Promiscuous combination of ideas," Hauser explained, "allows the mingling of different domains of knowledge such as art, sex, space, causality and friendship thereby generating new laws, social relationships and technologies."

3. Mental symbols -  Mental symbols are our way of encoding sensory experiences. They form the basis of our complex systems of language and communication. We may choose to keep our mental symbols to ourselves, or represent them to others using words or pictures.

4. Abstract thought

Abstract thought is the contemplation of things beyond what we can sense.
