It’s wonderful to see this list light up so passionately. Rumours of the death 
of safety-critical systems debate were exaggerated. 
Your detailed breakdown of what a software and systems engineer should know 
resonated with me both for what it includes and excludes. It’s correct but 
incomplete. Looking back on 50 years in systems engineering I’ve concluded 
that something was missing from my education. You know something is missing 
when you’re flummoxed - faced with a situation where you have no analytical 
skills to guide your next move. For me, it was ethical dilemmas and people 
problems. But this is a reductionist view, the bigger picture is: I was given 
no grounding in philosophy. No one taught me how to live as an engineer. This 
ignorance was annoying then but is deadly now as engineers face mind-bending 
judgement calls such as, “Is this AI sentient 
 ergo it’s in a safe state?” 

I refuse to retire and go quietly so I’ve been reading philosophy and trying 
to stay on top of developments in artificial intelligence (an impossible 
task), specifically its application to safety critical systems - Tesla and the 
like. It’s an exciting but horrifying experience. Exciting due to the endless 
utility of the six artificially intelligent agents I converse with every day 
and horrifying when I witness a neural network deployed to drive an 
automobile. It’s doing my head in that a giant blob of parameters (a neural 
network) has replaced a highly deterministic multilayer control systems 
architecture the like of which we have been refining for the past 50 years.  
This blob is not assembled subject to an unambiguous, complete and correct 
requirement specification and can therefore not be validated with a suite of 
human or machine-executable, module, unit, integration and systems tests. All 
we have is actors such as Mira Murati (Chief Technical Officer of OpenAI) 
shrugging, “Aw shucks, we don’t understand why it works so well.” Or gems from 
the likes of tech dudes such as Elon Musk, “Full Self-Driving V12.5 is good to 
go, it no longer spills my coffee.”

Clearly, we are witnessing the death of determinism in control systems. It is 
our sacred duty as professional engineers to turn this trend around “for the 
good of mankind”. This is not a fad. Neural nets are a postmodern fact of 
life. You can take a Robotaxi in San Francisco, Los Angeles, Las Vegas, Austin 
and Phoenix.

Where do we start? Just as neural nets deployed in safety-critical 
applications need to be wrapped in a postmodern variant of systems engineering 
discipline so do engineers need an upgrade to their educational wrapper -  a 
solid grounding in philosophy at the core of all undergraduate engineering 
courses. And it must be COMPULSORY, not an elective. 

Over the years, in an unexamined creeping manner, engineers have accumulated 
massive power. We have designed nuclear bombs placing the world on a hair-
trigger for the insanity of unwinnable nuclear war. Military technologists 
freely admit that the Ohio-class submarine is a greater threat to the planet 
than a meteor. We build deep fake tools that can mess with the minds of 3 
billion people overnight. Artificial general intelligence will put this power 
on steroids, we therefore need to teach engineers how to wield it with the 
wisdom wrapped in philosophy. My thesis is that wisdom can and must be taught 
not left in the nebulous netherworld we call experience where the test comes 
first and the lesson later.  Some decisions must be right the first time, 
there being no opportunity for continuous improvement in a dead radioactive 
planet populated by 6 billion corpses. 

Graduate engineers need to be celebrated not only for the equations they can 
solve but also for who they are; educated individuals, possessed of open, 
calm, self-controlled, stoic, stable, moral, measured, rational and logical 
minds with an unshakeable commitment to the profession, virtuous, incapable of 
committing an immoral act; not as culturally illiterate, laisser-faire, 
technical automatons (a guaranteed outcome of your current curriculum Steve). 
All of the above are learned behaviours that are reinforced by experience but 
will struggle for an engineer’s attention unless the frameworks and principles 
are taught and valued at the engineering origin - the University.

Your summary curriculum is engineering hygiene, necessary but not sufficient. 
We need to move our undergrads beyond algorithms to engage with the elements 
of our humanity that non-engineers are merrily moving into silicon. The 
squishy nondeterministic stuff that goes on in the brain. 
The engineering education must instil a state of mind - a certainty in “who am 
I?”. Over the years we have evolved from spot problem solver, to systems 
designer, to where we find ourselves today - Cognitive Systems Designer, a 
professional specializing in the creation of intelligent systems that 
replicate or enhance cognitive functions, such as perception, learning, and 
problem-solving, by utilizing insights from philosophy, psychology, 
neuroscience and artificial intelligence.

The problem is that much of the customer-facing AI product development work is 
currently being led by non-engineers. Look up Dennis Hassabis, Sam Altman, 
Jack Clark et al. they are neuroscientists, computer scientists and 
philosophers.  Brilliant people but lacking an engineering mindset, as 
evidenced by safety as an afterthought in chatbot development. I would be 
surprised if any of them has ever heard of the concept of Functional Safety. 
My point is that the brain that works at the AI system product coalface must 
have an engineering mindset with philosophical reasoning embedded. Designers 
make decisions that can't or won't be reversed especially if they increase 
shareholder value. Frances Haugen testified that Facebook knowingly left 
algorithms injurious to user mental health in the mix to preserve cash flow. A 
thought experiment: what if the designers just said, "No!" Where would you 
find the courage to do such a thing?
 
And so we have come full circle to a place where ancient philosophy offers a 
wealth of insights that can be practically useful in this cognitive state. My 
humble suggestions are:
 
1. Socratic Method: This technique emphasizes dialogue and questioning to 
stimulate critical thinking and illuminate ideas. Cognitive Systems Designers 
can use this method to refine their ideas, evaluate assumptions, and enhance 
problem-solving through collaborative discussions. Postmodern Systems 
Engineering is a team sport that will welcome synthetic agents and assistants.
 
2. Aristotelian Virtue Ethics: Aristotle's focus on virtue ethics encourages 
designers to consider the moral implications of their work. This perspective 
fosters a commitment to creating systems that prioritize human well-being, 
flourishing, and responsible use of technology. “For the benefit of mankind” 
means, that when interests conflict, we report to mankind, not our political 
or commercial masters. The courage to hold this line is a function of a clear 
view of who you are.
 
3. Realism vs. Idealism: Philosophical debates on realism and idealism can 
inform Cognitive Systems Designers about the nature of perception and reality. 
Understanding how different perspectives affect cognition can help in 
designing more intuitive systems. The naive engineer will be shocked to 
discover that reality is largely a function of personal perception, with the 
possible exception of gravity.
 
4. Teleology: The concept that everything has a purpose can guide designers in 
understanding the intended functions of cognitive systems. By clarifying the 
goals of their creations, designers can align technology with human cognitive 
processes and needs.
 
5. Mind-Body Dualism (Descartes): Exploring the relationship between the mind 
and body can inform the development of interfaces in cognitive systems that 
account for the physical and psychological experiences of users, enhancing 
user engagement and interaction. Research indicates that a component of our 
wisdom resides in the body, independent of the mind. For example, the body 
does not want to lie – evidence the success of polygraph technology.
 
6. Stoicism: This philosophy emphasizes resilience and rationality in the face 
of challenges. For designers, it can inspire a focus on creating robust 
systems that empower users to cope with uncertainties and enhance decision-
making. In bad situations, engineers need to stay calm and rational when 
surrounded by panic. Stoicism provides simple tools to deal with high-stress 
events. Marcus Aurelius instructs us, "It’s not the event that sparks panic 
it’s how you react to it and this is under your control."
 
7. Phenomenology: The study of experience and consciousness can provide 
valuable insights into user interaction with cognitive systems. Understanding 
how people perceive and interpret their experiences can lead to more 
empathetic and effective designs.
 
8. Pragmatism (William James): The pragmatic approach encourages designers to 
consider the practical outcomes of their technologies. Focusing on real-world 
applications and user impact can help create cognitive systems that are both 
functional and meaningful. What was the designer of the B61 nuclear bomb 
thinking when he provided for configurable yield (0.3 to 340 kilotons). “Aw 
shucks, if we’re mildly upset we’ll kill a few thousand enemy but if we’re 
really angry we can smoke 2 million.” 
 
And so I beat on (with apologies to F Scott Fitzgerald), a boat against the 
current, drawing the profession back into the past to assure its future. It 
could be an act of stupid courage, attempting to nudge a local University in 
this direction through my association with a colleague who lectures in their 
postgraduate engineering stream. 

Here’s hoping that all of the above will attract some comment from this list. 
In particular from the university educators amongst us. I read many American 
universities are aggressively pursuing AI in education. Is anyone pursuing 
philosophy for engineers?
 
And to the freshman engineer a warning, suit up and front up to Marcus 
Aurelius, Epictetus, Seneca, Aristotle, Socrates 
 et al. Listen to what they 
have to say, you don’t want to find yourself in this situation:
 
A broken wing rocks on the sand
Beside a far-off sea
In pitch black faith was placed in men
Christ
One of them was me!
 
Cheers
Les

PS: A practical suggestion. Read Ryan Holiday, The Daily Stoic. It’s not 
rocket science, five minutes a day could transform you into a Philosopher 
Engineer.
