## Belief System API

### Retrieving a Belief System

```python theme={null}
belief_system = epistemic_me.SelfModel.retrieve_belief_system(id="self_001")
```

Response:

```python theme={null}
{
   "observation_contexts": [],
   "beliefs": []
}
```

### Belief System with Metrics

```python theme={null}
belief_system = epistemic_me.BeliefSystem.retrieve_belief_system(
    id="self_001", 
    metrics=True
)
```

Response:

```python theme={null}
{
   "observation_contexts": [],
   "beliefs": [],
   "metrics": {
      "total_beliefs": 0,
      "total_falsifiable_beliefs": 0,
      "total_causal_beliefs": 0,
      "total_belief_statements": 0,
   }
}
```

### Conceptualized Belief Systems

```python theme={null}
belief_system = epistemic_me.SelfModel.retrieve_belief_system(
    id="self_001",
    conceptualize=True
)
```

Response:

```python theme={null}
{
   "observation_contexts" : [
      {
         "id" : "obs_context_001",
         "name" : "Sleep and Heart Rate Variability",

            }
         }
