The Internal Map: Understanding the Nature of Belief

For our latest entry on iversonsoftware.com, we delve back into the core of Epistemology to examine the engine of human conviction: The Nature of Belief. In a world of data streams and decision trees, understanding what constitutes a “belief” is the first step in auditing our internal software.

At Iverson Software, we specialize in references—external stores of information. But how does that information move from a screen into the “internal database” of your mind? In philosophy, a Belief is a mental state in which an individual holds a proposition to be true. It is the fundamental building block of how we navigate reality.

If knowledge is the “output” we strive for, belief is the “input” that makes the process possible.

1. The “Mental Representation” Model

Most philosophers view a belief as a Mental Representation. Think of it as a map of a territory.

  • The Proposition: A statement about the world (e.g., “The server is online”).

  • The Attitude: Your internal stance toward that statement (e.g., “I accept this as true”).

  • The Map is Not the Territory: A belief can be perfectly held but entirely wrong. Just as a corrupted file doesn’t stop a computer from trying to read it, a false belief still directs human behavior as if it were true.

2. Doxastic Voluntarism: Can You Choose Your Beliefs?

A major debate in the philosophy of mind is whether we have “admin privileges” over our own beliefs.

  • Direct Voluntarism: The idea that you can choose to believe something through a simple act of will. (Most philosophers argue this is impossible; you cannot simply choose to believe the sky is green right now).

  • Indirect Voluntarism: The idea that we influence our beliefs by choosing which data we consume. By auditing our sources and practicing critical thinking, we “train” our minds to adopt more accurate beliefs over time.

3. Occurrent vs. Dispositional Beliefs

Not all beliefs are “active” in your RAM at all times.

  • Occurrent Beliefs: Thoughts currently at the forefront of your mind (e.g., “I am reading this blog”).

  • Dispositional Beliefs: Information stored in your “hard drive” that you aren’t thinking about, but would affirm if asked (e.g., “Paris is the capital of France”). Most of our world-view is composed of these background dispositional beliefs, acting like a silent OS that influences our reactions without us noticing.

4. The Degrees of Belief (Bayesian Epistemology)

In the digital age, we rarely deal in 100% certainty. Modern epistemology often treats belief as a Probability Scale rather than a binary “True/False” switch.

  • Credence: This is the measure of how much “weight” you give to a belief.

  • Bayesian Updating: When you receive new data, you don’t necessarily delete an old belief; you adjust your “confidence score” based on the strength of the new evidence. This is exactly how modern machine learning and spam filters operate.

Why the Nature of Belief Matters to Our Readers

  • Cognitive Debugging: By recognizing that beliefs are just mental maps, you can become more comfortable “updating the software” when those maps are proven inaccurate.

  • Empathy in Communication: Understanding that others operate on different “internal maps” helps in resolving conflicts and building better collaborative systems.

  • Information Resilience: In an era of deepfakes, knowing how beliefs are formed allows you to guard against “code injection”—the process where misinformation is designed to bypass your logical filters and take root in your belief system.
