We each have moments throughout our day when we find our mind gently wandering. I’m sure I’m not alone in appreciating these periods of thought; the rhythms of the mind slow as we carry out our mundane day to day tasks and our thoughts become more reflective. We allow our mind to drift along, to take little eddies away and back until one line of thought takes our attention and we choose to explore this more deeply. It’s good to savour these moments, they are moments of growth, of re-evaluating and questioning our beliefs, of reflexivity as we place ourselves in the world and consider how we impact those around us.
So it was this morning, as my thoughts enquired why it is that we as humans vary in our regard for nonhuman animals. What causes someone to see the value of other’s lives, to accept the paradigm of personhood in other than human beings, that they have their own experiences and subjectivity, and yet for another to dismiss this concept as fallacy?
There may be influences from cultural and social backgrounds, peer groups and online sources that culminate in structuring beliefs, but we also hear a voice within us which questions the authenticity of these beliefs and advocates for novel thoughts and ideas to play through our mind. Being entrenched in a pattern of thinking closes the door to exploring the world from new perspectives; we may ultimately draw the same conclusions but we have had the opportunity to venture forth and seek a different path with renewed and optimistic vigour. From that place in our mind’s eye, we have expanded our outlook whichever conclusions we draw.

The concept of other-than-human personhood can be difficult to accept, but if we work back through our evolutionary past, we find connections that bind humans and nonhumans together far more than we may possibly realise. I am going to borrow some of Peter Godfrey-Smith’s (2020) work to evidence this. Memory is an important aspect of how our mind processes; we remember facts (semantic), procedures, working memory – the manipulation of ideas and images, and episodic memory or remembering experienced events.
Interestingly, it is thought that episodic memory includes imaginings of the future; the hypothesis of constructive episodic simulation. Godfrey-Smith also talks about ‘off-line processing’ which basically describes my thought processes in the first two paragraphs – the ability to step forward, backwards, or sideways in our thoughts to create ‘alternative presents’ (p. 253), of both being here and elsewhere.
Now we venture into more fascinating territory – that of sleep, and in particular the alternation of REM and slow wave sleep. Humans are known to dream when in the REM period of sleep, and yes, we have probably all observed the animals who share our lives showing movements and vocalisations which we would associate with dreaming. However, cephalopods, who split away from our evolutionary linage 600 million years ago, for example, cuttlefish and octopuses, also show colour and pattern changing responses in their sleep. Could this mean that they too are processing memories and actioning behaviours unconsciously? Certainly, it is now becoming more recognised that sentience travels far further back into the evolutionary process than once thought, and alongside sentience, we have to consider the emotional lives of nonhuman animals.
The balance of sentience, cognition and consciousness is not necessarily on a continuum, animals may possess these attributes in different degrees but possession of any should be enough to make us pause for thought. The subjectivity of another through the capacity to experience and respond to the world raises the conundrum of personhood. To my mind, why not assume personhood in others unless there is absolute, rather than arbitrary, proof to the contrary.
