A while back, I indicated that I would start posting about my own ideas on philosophy. But I have not posted much since then. This is an attempt to resume that effort.
My own philosophy appears to be a variety of conventionalism.
I have previously stated that I am a behaviorist. That does not change. I see social conventions as, primarily, behavioral conventions. A simple example is the convention that we should drive on the right side of the road. This is a convention about behavior.
What is conventionalism?
According to Wikipedia:
Conventionalism is the philosophical attitude that fundamental principles of a certain kind are grounded on (explicit or implicit) agreements in society, rather than on external reality.
Conventionalism appears to be controversial within philosophy. There is fairly broad acceptance that language is conventional, though there are disagreements about that, too. Henri Poincaré was conventionalist about geometry, which seems right to me. Some have argued that mathematics is conventional. That is more controversial, and many philosophers believe that Quine refuted that position in his “Truth by convention”. I’ll not that I disagree with Quine, and perhaps I’ll discuss that in a future post.

As suggested in the previous post, I think of a cognitive system as an information system. In this post, I want to look at a particular information system, namely a video camera.
Let me be very clear here. I do not think that a cognitive system is very much like a video camera. Rather, I see them as very different. However, by looking at a video camera, we can examine some basic principles that seem to be common to all information systems, including human cognitive systems.
In particular, we want to look at:
- the input phase, where data is gathered;
- the organization phase, where the data is assembled together;
- the output stream — the final output information.
The input phase
For the video camera, the data is gathered into a pixel map. I am going to describe this as categorization. That might seem a strange term to use for generating a pixel map, so I should first explain why I am using that term.

As cognitive agents, we inform ourselves about the world and we use that information to control our behavior. We also report information to others, as I am doing in this blog post. This post is part of a series on my own philosophy. It will mainly be about the meaning of the word “information” as I use it when discussing cognition.
I shall be using “information” to refer to what is often called Shannon Information, after the work of Claude Shannon. The term “Shannon Information” has come to mean information in the form of a structured sequence of symbols, such as a natural language sentence or a data transmission stream on the Internet. Shannon’s own research was not limited to the use of transmission in discrete units (such as words or bits), but its main use is with discrete units.
Shannon information is often criticized as being an entirely syntactic view of information. Shannon was concerned with communication, with getting the stream of discrete symbols from the source to the destination. His theory is not concerned with issues of meaning or semantics.
