Why the most important knowledge you possess is impossible to put into words
In short: Michael Polanyi, a polymath who bridged chemistry and philosophy, argued that our greatest achievements rely on tacit knowledge—the skills we master but cannot fully explain. He contended that science, like a free market, flourishes only when independent thinkers coordinate through open debate rather than central authority.
Born in 1891, Michael Polanyi was a Hungarian-British intellectual whose career spanned physical chemistry, economics, and philosophy. After pioneering theories in fibre diffraction and dislocation in metals, he turned his attention to the social sciences. His shift was prompted by witnessing the rise of central planning in the Soviet Union, where he observed that state-directed research—as described by Nikolai Bukharin—threatened the very nature of scientific inquiry. Polanyi argued that science is a spontaneous order, where scientists act as independent agents whose personal judgments and commitments drive discovery.
Central to Polanyi’s philosophy is the concept of tacit knowledge, which he identified as his most significant discovery. He posited that we know more than we can say, a reality evident in skills like riding a bicycle or playing an instrument. This awareness is not merely practical; it is foundational to all perception and meaning. In his seminal work, Personal Knowledge (1958), Polanyi rejected the positivist view that science can be reduced to mechanical rules. Instead, he argued that all knowledge claims rely on personal commitments and that a knower is an active participant in the universe rather than a detached observer.
Polanyi also challenged the reductionist worldview inherited from Galileo, advocating instead for the theory of emergence. He suggested that reality exists in several levels of causality, where higher-level principles—such as consciousness—constrain lower-level physical properties. He warned that attempting to reduce these higher realities to lower ones leads to a moral inversion, a pathology he identified in ideologies like Marxism. By insisting that truth, justice, and beauty are not merely subjective, Polanyi sought to defend a free society that values the pursuit of spiritual ends over a hollow, value-neutral existence.
His influence extended far beyond his own lifetime, shaping the work of thinkers like Thomas Kuhn and Hubert Dreyfus. By asserting that all knowing is fallible and deeply personal, Polanyi provided a robust defense of intellectual freedom. He maintained that a society that ignores the role of passionate commitment in human achievement risks falling into nihilism, as it discards the very ideals that motivate our highest potential.
