Goals in the machine

PART I: Purpose exiled

According to Plato, our theories about the world should ‘carve nature at its joints’. Telos, the once plausible idea that purpose is a part of the natural order of things, has been steadily banished with the triumph of successive scientific theories in the modern age, culminating in the mechanism of evolution by natural selection and its accompanying metaphor of the blind watchmaker. Here, fitness, defined as the ability to survive and reproduce, is the sole arbiter of design in nature, acquired through so much as the blind lotteries of genetic variation. The momentary surprise that one even scientifically inclined feels at some marvelous specimen of evolution, for example the finesse of a Gray’s leaf insect mimicking not just a leaf but its brown and dying spots to better camouflage against predation (https://www.biodiversitysingapore.com/in-focus/), is to be utterly dispelled by belief in the creative potential of random mutations offering themselves up to selection pressures over geological spans of time.

Emergence: ‘more is different’

Contemplating how mind and intelligence came to be within such a setting presents further aesthetic tension (the mind of everyday experience exclaims, that sounds crazy!). Emergence (1) is a relatively recent concept that purports to explain phenomena like mind while undergirding it with a non-negotiable physicalist ontology. The essence of emergence is that through scaling of individual components, a system acquires so-called novel bases - new foundations upon which regularities can be encoded that were not possible at the lower levels. For example, neurons individually fire action potentials based on the threshold dynamics of local stimuli. Collectively however, groups of neurons fire according to abstract patterns termed ‘basins of attraction’ that represent long-range stable states and may be foundational to concepts like memory (2). Conway’s game of life, anchored by a set of very simple rules, presents a powerful illustration of this dynamic:

There is a folk account of emergence popular with science writers that goes something like this: while the physics of the system is completely known, predicting what is going to happen is near-impossible just with physics, because there is novel stuff happening at ‘higher’ levels. Importantly, no God or designer directed the organization at the higher levels, but it is not discernible anywhere else.

What does it mean to take seriously a universe in which purpose is nowhere fundamental, yet everywhere invoked?

PART II: Purpose reconsidered

And yet, there are radical perspectives afoot. Without invoking external designers, some contemporary thinkers argue that natural selection and emergence may not exhaust the explanatory story. Developmental biologist Michael Levin (3) and evolutionary scientist Richard Watson (4) suggest that the mechanisms generating variation themselves may be structured, biased, or even goal-directed, analogous to neural or social learning processes.

Levin introduced so-called biobots, which are multicellular living structures assembled from human lung epithelium. Biobots exhibit coordinated movement and problem-solving in novel environments despite having no evolutionary lineage that selected for such behaviors (5). Adaptation appears immediately, as if the system were exploring possibilities rather than stumbling upon them.

Does this point toward a universe where purpose was never fully absent to begin with?

Join us this Saturday as we grapple with where purpose truly lies in nature.
