Each year on World Philosophy Day on 21 November, people around the globe are invited to reflect on the role philosophy plays in shaping our understanding of the world.

Philosophy, meaning ‘love of wisdom’, is interpreted differently by different people, and this diversity of interpretation is one of its most enduring strengths. For some, it’s an intellectual pursuit, a way of seeking deep truths about existence, morality, and knowledge. For others, it’s simply a practical guide to living more meaningfully.

“Philosophy is an attempt to make sense of life, the universe, and everything, through human reason,” says Associate Professor Loy Hui Chieh from the Department of Philosophy at the NUS Faculty of Arts and Social Sciences.

For final-year Philosophy major Christopher Chin, the understanding of philosophy challenges our norms and forces us to grow, while final-year History and Philosophy double major Sofia Marliini Heikkonen believes it offers the privilege of interrogating life.

Dr Daryl Ooi, a lecturer at the Department of Philosophy agrees, saying that, “Philosophy is one of the activities humans practice when we’re trying to figure out how to relate and orientate ourselves to this exciting, complex and confusing world we live in.”

Fundamentally, however, philosophy is a way of thinking that cuts to the heart of what it means to be human.

‘Confucius says…’

The foundational ideas established by many great thinkers and philosophers like Socrates, Plato, and Aristotle have shaped our understanding of the world. These renowned philosophers pioneered the use of reason and logic to explore the workings of the universe while delving into the complexities of human morality.

Although Confucius lived around 500 BC, some 2,500 years ago, today he remains synonymous with wisdom and insights into life. The expression ‘Confucius says...’ is often cited when imparting general wisdom, exemplifying how philosophy transcends time and generations.

In the context of retaliation, for example – whether in war or conflict – one might consider Confucius’ wise words before determining a course of action: ‘Before you embark on a journey of revenge, dig two graves.’

“A common misunderstanding about philosophy is that it’s purely abstract and impractical, dealing only with questions that have no real-world impact. In reality, many of the questions discussed in philosophy have significant real-world implications,” said the Department’s Assistant Professor Song Moonyoung.

A compass for the modern world

Some may question the relevance of philosophical thinking today given the proliferation of science and technology that comes with the promise to simplify our lives and even make decisions on our behalf. Philosophers, however, agree that as the world changes rapidly through technology and social upheaval, the role of philosophy will only grow in importance.

Dr Ooi believes that as long as humans continue to ask big and narrow questions about the world today and attempt to make sense of their beliefs, values, emotions and ideas, philosophy will continue to endure.

Likewise, Asst Prof Song believes philosophy is even more relevant in a time when science and technology are at the forefront. “Philosophy encourages us to consider the ethical implications of technological advancements, such as artificial intelligence (AI) and genetic engineering, and guides us in making thoughtful, responsible choices about their development and use,” she says.

Assoc Prof Loy views philosophy as one part of a much larger repertoire now available to modern humanity. Its strength stems not from disregarding developments in other fields and domains, but from working in tandem with them. “Take artificial intelligence or AI for example. I have been drawn to research projects that look into how AI will affect education because it involves contributions from social science, data science, computer science and many others,” he says.

Related to that is the complex task of developing a practical governing framework for the development of AI and, even more critically, the ethics of its application. Dr Ooi, himself a former student of Assoc Prof Loy, says that the intricacy of such tasks is precisely the reason we recognise the value of interdisciplinary education.

He explains, “We need specialists from different disciplines to work together – and philosophers certainly have much to contribute towards the development or shaping of any kind of moral framework that would support the development and application of AI. Get a philosopher in the room to ask questions about ethics and morality, or even what it means to be human. This will trigger some incredibly meaningful and important conversations, and sometimes, you may even get something like an answer!”

Assoc Prof Loy, who is also Vice Dean (Academic Affairs) for NUS College, adds that he sees philosophers as some of the most interested and equipped people to discuss complex issues, not necessarily by supplying any ready-made “moral framework”, but simply by being people who are keen on thinking very carefully and working with experts from other technical disciplines.

Expanding on this perspective, Asst Prof Song, who specialises in the philosophy of art, notes that the increasing integration of AI into our lives invites us to reflect on what truly defines humanity. The answer may not lie in what we can do better than AI. Instead, what makes us special may indeed be our limitations, such as the fact that humans have physical bodies that inevitably age and perish.

She adds, “These limitations give human achievements – such as artwork – a completely different meaning, even if, on the surface, they may look similar to AI-created products.”

In recent years, mental health has become another area where philosophy provides a unique lens through which we can understand and address psychological well-being. Commenting on the role of philosophy or philosophical ideas in mental health treatment or in helping people cope with mental health challenges, Dr Ooi highlights the increasing attention given to the therapeutic value of philosophical ideas.

He says, “The idea of ‘care for the soul’ and ‘care for the self’ is a historically important one that is of immense relevance for us today, and there are many important philosophical questions that we can ask that are highly relevant to issues surrounding mental health today. For instance, how do we understand the obligations individuals have to care for one another, should education systems have an ethical responsibility to ensure that students do not suffer certain harms, or how can individuals and societies understand values such as ‘respect’ and ‘dignity’ so that those values shape the way humans treat each other?”

Many of the tools employed in philosophy and the intellectual dispositions it nurtures have broad applications – particularly in instances where careful reasoning is needed or when navigating any situations without any clear precedents. This intellectual rigour is what has drawn some undergraduates to take up Philosophy to complement other fields of study, recognising the value of the discipline’s critical thinking and reasoning skills.

Joan Lim, a final-year Philosophy and Life Sciences double degree student, was first introduced to Philosophy in secondary school.

Joan was part of the pioneering batch at the College of Humanities and Sciences and says she jumped at the opportunity to take two contrasting degrees, believing in the importance of an interdisciplinary education to gain a deeper understanding of our increasingly complex and interconnected world.

“I feel that the disciplines are complementary because science needs to be ethically applied, and the humanities benefit from the real-world grounding from the sciences.  Fields such as AI and sustainability consider the best ways to apply science and technology such that harm may be reduced; a purely scientific approach may lack that moral analysis.”

Armed with the insights gained from her philosophy studies, Joan is looking for a career that will allow her to contribute to the field of sustainability, another existential challenge for mankind. “I hope to provide an ethical and logical lens for analysing complex issues such as sustainability and AI, but also in the vein of the philosophical training that I have received here at NUS, one which is empathetic and kind,” she says.

Marliini, who has always felt very strongly about diversity, representation and inclusivity, is looking for opportunities to build bridges within the communities around her. “I'm still discovering what exactly my career will look like post-graduation, and what excites me is the prospect of fostering environments where people feel empowered, accepted and connected.”

Beyond its influence on society, Christopher believes that philosophy’s teachings have made an impact on his personal relationships.

“The clarity and discernment that philosophy teaches us should be channelled towards goodness. It reminds us to be compassionate because as (Chinese Confucian philosopher) Mengzi suggests, all humans have the heart of compassion. Whatever the psychological pain, I believe being compassionate, empathetic, and present should be our first response,” says Christopher, reflecting on the wisdom drawn from philosophy when dealing with friends and loved ones in need.

Enduring influence in shaping humanity

From artificial intelligence to mental health, philosophy offers a powerful lens for understanding and navigating the complexities of contemporary life. Whether for those immersed in academic inquiry or individuals looking for clarity in a fast-paced world, philosophy provides a space for thoughtful reflection, grounded in the search for truth and meaning.

Assoc Prof Loy has noted how students get to have a lot of intellectual fun reading philosophy while giving them leverage for other intellectual pursuits.

“Everyone stands to gain from the process of philosophical inquiry,” says Marliini. “The skills we learn are beneficial far beyond academics because philosophy at its core teaches us how to hold space for different perspectives while maintaining the rigour to examine and articulate our own.”

In the words of Peter Singer, one of the most highly regarded modern philosophers alive today, “Philosophy ought to question the basic assumptions of the age. Thinking through, critically and carefully, what most of us take for granted is, I believe, the chief task of philosophy, and the task that makes philosophy a worthwhile activity.”
