Abstract senses are about attaching context to the world as seen by our six senses. For humans the fight for a reasonable living standard is function of – What you know and how you learn more about the outside world -Applying your understanding of the outside world

When Homo sapiens shopped for senses, he didn’t buy the luxury package. He chose good-enough sight, fit-for-purpose hearing, modest smell and taste, and high-fidelity touch in the fingers. Later he built telescopes, microphones, flavourings, and instruments to upgrade the set.

Living things rely on their senses to survive—but humans go one step further. We don’t just sense the world; we derive meaning in a more extensive way than any other species on the planet. This chapter explores how that ability evolved—and how we can use it better.

To understand how we think, act, and struggle today, we need to look deep into our biological past. Our brains — the tools we use to reason — are the product of millions of years of evolution. The path to modern humans is marked by survival, adaptation, and legacy.

“You are what you eat.” usually refers to poor dietary habits. On a deeper level, it points to something more profound: the relationship between energy intake and its use. Nowhere is this trade-off clearer than in the cost of running a brain.

Humans brain carries the legacies evolution : Older systems (hypothalamus, amygdala, brainstem) = System 1 survival engine. Newer systems (neocortex, prefrontal cortex) = System 2 deliberation and planning. Recognizing this dual architecture helps explain both strengths and vulnerabilities: reflexes saves us in an instant, but can also mislead us in the modern world

This post considers human intelligence. While other animals such as octopi and birds show impressive problem-solving, only humans scaled intelligence into a planetary force. To apply the principles of observation, consequence, and action, I start with ten fixed points in Earth history.

As part of further training by my firm as an engineer I attended a Kepner-Tregoe seminar. This introduced me to a strategy for critical thinking. Later in Germany I attended a course on “How to Give Feedback Back” — this brought my attention to the pattern of observation consequence and action.
