Across the previous four Entries, the human being has emerged as a living system carrying many influences from the past.
Genes contribute to our starting conditions. The body and nervous system continuously process signals. Previous experience shapes present responses. Memory and the story we tell about ourselves continue to influence how we interpret what is happening.
So where does freedom fit into all of this?
One way to approach it is through our capacity to adjust.
Many responses form very quickly.
We may tense up in a familiar situation, avoid something once associated with discomfort, fall back into an old habit, or repeat a response we have relied on many times before.
These reactions have a history.
Yet the nervous system can continue learning from new experience. A once-powerful response may weaken over time. One habit can gradually be replaced by another. A situation previously associated with fear can come to be handled differently as conditions change.
This capacity for change is part of the nervous system’s ability to adjust through experience, often referred to as plasticity.
We cannot always control the first response that appears.
An emotion may arise quickly. The body may shift state. A thought or impulse may surface almost automatically.
What we can learn is how to handle what happens next.
We may notice the reaction, delay acting on it, reassess the situation, or choose a different response from the one we used before.
This ability is not equally available at all times. Fatigue, stress, illness, environment, and many other factors can affect it.
As our ability to regulate a response grows, the range of available choices can grow with it.
Every choice occurs under particular conditions.
We bring the body we have, the nervous system we have, our memories, our circumstances, and everything we have learned up to that point.
Freedom does not exist in complete isolation from those influences; it appears in how we respond to what is already present.
Two people facing the same situation may choose differently. The same person, after years of learning and change, may also respond very differently from an earlier version of themselves.
The past leaves tendencies behind.
An experience may make us more cautious. A learned skill may give us more options. An earlier mistake may help us recognize something worth avoiding. A response that once served us well may eventually become a habit that no longer fits.
Memory retains traces of the past and continues to influence later choices.
We learn because something of the past remains with us. As we learn to respond differently, the way the past affects the present can change as well.
The Ascent of Memory began with DNA as a form of biological information storage, then moved through genes, the body, the nervous system, personal memory, consciousness, and the sense of self.
At every stage, the past leaves an influence, but the strength and form of that influence can change.
The body continues to adapt. The nervous system continues to learn. Memories are updated. Our understanding of ourselves can be revised. Responses repeated for years can change.
We do not begin each day from zero, and we are not completely locked into what we already carry.
Between those two conditions is a human being still learning, changing, and choosing how to act.
