Abstract A mark of the cognitive should allow us to specify theoretical principles for demarcating from non-cognitive causes behaviour in organisms. Specific criteria are required settle question when evolution life cognition first emerged. An answer this however avoid two pitfalls. It overintellectualising minds other organisms, ascribing them capacities which they have no need given lives lead within niches inhabit. But equally it do justice remarkable flexibility and adaptiveness that can be observed microorganisms not a nervous system. We resist seeking explanations simply because an organism fails exhibit human-like feats thinking, reasoning problem-solving. will show how Karl Friston’s Free-Energy Principle (FEP) serve as basis avoids twin pitfalls or underestimating achievements evolutionarily primitive The FEP purports describe organisation any must instantiate if is remain well-adapted its environment.

How can the free energy principle contribute to research on neural correlates of consciousness, and scientific study consciousness more generally? Under principle, should be defined in terms dynamics, not states, complemented by computational – probabilities encoded states. We argue that these restrictions brighten prospects a explanation addressing two central problems. The first is account for absence sensory stimulation behaviour. second allow possibility systems implement computations associated with without being conscious, which requires differentiating between merely simulate conscious beings are themselves. Given notion computation entailed we derive constraints ascription controversial cases (e.g., behaviour). show this also has implications what it means be, as opposed system.
