The Wisdom of Subtraction
Knowledge and wisdom are both goods of the mind that human beings habitually pursue. Yet the Eastern tradition holds that, in the cultivation of a person, profound wisdom matters more than wide learning. That judgment matters enormously for those of us living in an age of information overload.
In the “Nourishing the Lord of Life” chapter of the Zhuangzi there is a famous passage: “My life has a limit, but knowledge has none. To pursue what is limitless with what is limited—this is perilous indeed!” For most people, Zhuangzi’s sigh is an acknowledgment of human finitude, and it carries an unmistakable note of melancholy. If all knowledge were held to be equally important and therefore equally worth pursuing, then a finite life could never exhaust an infinite store of it, and the unhappy outcome would be settled from the very start. Yet for the cultivation of a person, the pursuit of infinite knowledge, however heroic in spirit, is not a rational choice. Zhuangzi’s rejection of “pursuing the limitless with the limited” does not deny the value of learning useful things. It says, rather, that the way to a wisdom truly one’s own, a wisdom adequate to the ten thousand things of the world, lies not in the accumulation of knowledge but in the cultivation of discernment and understanding.
As we have all come to feel, ours is a knowledge age without precedent. Information multiplies exponentially, disciplines grow ever more specialized, instruments ever more precise; search engines, algorithmic feeds, paid knowledge products—a flood of learning surges toward us, threatening to swallow the world whole. And yet, strangely, the more we swim in this ocean, the more disoriented we become. The growth of knowledge has not filled the spiritual void, whether personal or collective. The more information the mind takes in, the more fragmented our thinking becomes, and the more the soul withers and shrivels. Clearly, knowledge beyond a certain point ceases to be a remedy that steadies the heart. Superfluous knowledge disturbs the mind and deepens our anxiety. The root of the problem lies not in knowledge itself but in whether we can turn the knowledge outside us into wisdom within us.
Recognizing the difference between acquiring knowledge and cultivating wisdom is, no doubt, the precondition for addressing this problem. In chapter 48 of the Daodejing, Laozi writes: “In the pursuit of learning, one gains daily; in the pursuit of the Way, one loses daily. Lose and again lose, until one arrives at non-action. Non-action, and yet nothing is left undone.” Learning requires accumulation—wide reading, patient study, steady increase. The pursuit of the Way asks for something else. What it seeks is not the quantity of knowledge outside us but the refinement of character and understanding within. It does not exclude knowledge, but its aim is not to enlarge the store of facts; it is to bring forth the wisdom by which we perceive and interpret the world and ourselves. Such wisdom is a set of relatively abstract principles. Because it fastens on no single problem or item of knowledge, it can generate flexible and varied responses to concrete situations. Hence the “non-action” that marks the limit of daily diminishing can, in practice, become “nothing left undone.”
Since the aim of the Way is not to possess infinite knowledge but to seek wisdom, the Daoist sage does not lose heart before boundless knowledge and a bounded life. Our own situation is precisely the opposite. We grasp for the greatest possible quantity of knowledge and scarcely notice whether we have gained any wisdom by which to live. Knowledge is hoarded like merchandise, and the storeroom where we keep our inner selves grows cluttered and chaotic.
Mere “decluttering,” or a flat refusal of knowledge, is not the answer; it drives people to the opposite extreme, into folly and arrogance. Only by dwelling on what we learn, by turning knowledge into wisdom, can we weave a wisdom of life that fits our own situation and recover the real meaning of living. The Analects records Confucius saying, in the “Xianwen” chapter: “The scholar of antiquity learned for himself; the scholar of today learns for others.” The ancients studied in order to strengthen their own understanding; the scholar of today studies in order to show off, or to satisfy the expectations of others. How much of our learning now is for ourselves, and how much is for others? We check in, post our notes, play the diligent student in the carnival of knowledge—and are buried in emptiness when we are alone. Knowledge acquired in this way makes us useful, but usefulness that is never examined ends by reducing a person to an inanimate tool—the very opposite of what it means to become fully human. Diminish daily in the pursuit of the Way, and set the heart at rest. What modern people lack is not knowledge but the willingness and the means to let what they learn touch their lives, to let it become a power of the soul, and to give birth to a wisdom that is truly their own. Such wisdom does not demand encyclopedic learning. It asks only for principles that a person can apprehend, test, and make their own—principles that bear reflection and can be put into practice. It fixes on no specialized problem, yet in any situation it can yield a fitting response. When wisdom becomes the ground of a life, a person is no longer held hostage by the infinity of knowledge, and finds composure in each passing moment
