**HumCat: The Human Category**

1. **The category of human beings**

**Starting point: Human thinking can be modeled as instantiations of thought patterns **

A thought can be regarded as the a instantiation of a kind of blue-print that we will refer to as a thought pattern, a thought-schema, or sometimes just a schema when the context is unambiguous. This is very similar to how databases are constructed by specifying a database schema and then populating the database by instantiating this (abstract) schema with (concrete) entries of data items – as well as with relations between some of these – in accordance with the rules and constraints provided by the schema.

1.1. **Human information**

The complementary view to Shannon’s perspective is the the human perspective on communication, which has been taken by a number of scholars. It is best represented by the famous definition of information given by Gregory Bateson (1972): “(the elementary unit of) information is a difference that makes a difference”. Hence, the first difference is mapped into the mind of the agent and combined with the cognitive state of the agent into the second difference.

According to Wikipedia, a pattern, is “a regularity in the world, in human-made design, or in abstract ideas. As such, the elements of a pattern repeat in a predictable manner.” From this perspective, a thought pattern could be thought of as a collection of mental models with predictable relations between some of them.

If we think of a difference as a form of pattern, then Bateson’s definition translates into “information is a pattern (of elementary units) that creates another pattern”. Moreover, this creation is due to the presence of a third pattern, namely the pattern that represents the cognitive state of the agent involved. We will often refer to the latter type of pattern as a cognitive schema.

Hence, we can expand Bateson’s definition in the following way:

*Information is a difference that makes a difference to me,
by allowing me to connect a pattern that is new to me
with the patterns that I know from before*.

Category theory is a universal pattern language for mathematics that has been developed during the last 75 years. It is concerned (in increasing order of importance) with patterns, relations between patterns and relations between such relations.

Since knowledge is expressed in terms of patterns, we can say that in Bateson’s model of information, knowledge is developed and “makes a difference” by connecting patterns. In category theory such connections are created by the construction of limits and colimits.

//////////////////////// **Quotes from Poincaré**:

Since half a century we have seen arise a crowd of bizarre functions which seem to try to resemble as little as possible the honest functions which serve some purpose….Nay more, from the logical point of view, it is these strange functions which are the most general….to-day they are invented expressly to put at fault the reasonings of our fathers….

— Henri Poincaré (1913)
