Long before we came along, with our brains and matcha tea, early life forms only had rudimentary sensory systems.
They detected and responded to environmental stimuli… things like light, pressure, or temperature.
These primitive systems didn’t “think” in any way we’d call cognition, they just acted.
They supported survival by guiding our behaviour: moving toward nutrients, away from toxins, or reacting to threats.
As nervous systems evolved, first as simple nerve nets (don’t even ask, it’s beyond me), then centralised structures, and eventually brains… those older, sensory systems (or embodied response mechanisms) didn’t disappear. They became the foundation of what we now experience as intuition, gut feelings, or emotional instincts. They operate waaaayy quicker than our rational thought because they’re rooted in ancient survival circuitry. For example, the amygdala and brainstem responses can trigger action before the cortex even finishes processing what’s happening (sometimes you know something before you know it).
So…intuition and feeling aren’t just “soft” or “irrational”, they’re actually evolutionarily ancient tools for survival and rapid decision-making. Rational thought is a newer layer built on top.
