Enough: Learning to Recognise It Through Chinese Philosophy

Last Easter, I flew to Portugal for a short trip. I still remember how I hesitated before going. It was one of the busiest weeks of the semester, yet everyone seemed to be travelling. Afraid of appearing like someone whose life revolved entirely around school, I joined the trip with a group of friends. But when I finally sat on that crowded tourist beach after the cheap early-morning flight, I realized that all I really wanted was a good night of sleep and a quiet afternoon reading under the cherry blossom tree near my apartment.  

My experience is not unique. What appears to be an individual choice is often shaped by expectations about what a "normal" life should look like. If consumption often follows expectations rather than genuine needs, the question is not simply how to consume less, but how to recognize what we truly need and when enough has already been reached. Without a language capable of expressing adequacy, expanding consumption can appear to be the only solution. In this sense, sufficiency concerns not only the planetary boundaries, but also our ability to live consciously rather than numbing ourselves with substitutes.  

Here, insights from Chinese philosophical traditions offer a valuable complement, linking self-awareness with a broader sense of social balance. One way to think about this is through three layers of reflection:  

First, inward reflection: Chan Buddhist practice embodies this layer through self-examination. A similar spirit appears in the Confucian saying "I examine myself three times a day", which highlights the practice of regularly reflecting on one's own actions and intentions. By "turning the eye inward," one examines the origins of desire: Why do I want this? What am I really seeking? When desire is questioned in this way, recognizing "enough" becomes less a restriction than a form of self-awareness.  

Second, balanced behaviour: The Confucian idea of ZhongYong, often translated as the "doctrine of the mean," refers to the ability to find the balance appropriate to each situation, including the capacity to recognize when something is sufficient. It is about recognizing the point where enough has been reached and stopping there.  

Third, connect with the wider community: Mohist philosophy introduces this social layer through a concept called JianAi, often translated as "impartial care", which emphasizes that in an interconnected society, the wellbeing of each individual is inseparable from the wellbeing of others. In a society guided by JianAi, individuals would be encouraged to act with consideration and restraint, recognizing what is appropriate and sufficient. From this perspective, caring for others' needs is not merely an act of moral generosity, but also a rational recognition that one's own wellbeing ultimately depends on the wellbeing of the whole.  

All three layers reflect the concept of planetary boundaries: while they define the inner boundary that serves as the initial momentum of behaviour, planetary boundaries define the outer boundary, a middle point between philosophy and science. Policy design should remove the obstacles that prevent people from choosing enough and provide inner and outer space for people to choose a way that aligns with both the inner and outer boundaries. We need multidimensional policy design to achieve this, such as cultivating sufficiency awareness from early education, and developing shared economies.  

Sufficiency is never simply an issue of efficiency or technology. It is a cultural question about how societies understand needs, desires, and wellbeing. It begins when people regain the ability to recognize when they already have enough, and when societies make that recognition possible.
