  This paper aims to justify the concept of natural intelligence, the type of
intelligence wider than human intelligence and its derivative, AI. I will argue
that the process of life is a cognitive process and that organisms, from
bacteria to animals, are cognitive agents. To justify these arguments, the
neural intelligence represented by the form of reasoning known as anthropic
reasoning will be compared and contrasted with types of intelligence explicated
by four disciplines of biology, relational biology, evolutionary epistemology,
biosemiotics and the systems view of life, not biased towards neural
intelligence. The comparison will be achieved by asking several questions that
probe the concepts of observers and true observers. To answer the questions I
will rely on a range of established concepts including SETI, Fermi's paradox,
bacterial cognition, versions of the panspermia theory, and some newly
introduced concepts including biocivilisations, cognitive universes, and the
cognitive multiverse. The key point emerging from the answers is that the
process of cognition, the essence of natural intelligence, is a biological
universal.
