Influential though Habermas has been, his case for deliberative democracy is undermined by its complete failure to address a point that Hayek made on numerous occasions. Though formal argumentation that takes place in democratic forums is one way in which people can learn from each other, it is by no means the most important. Far more significant is the capacity to observe the lived experience of other individuals and groups. Much of what we need to learn cannot be ‘put into words’ – it is ‘tacit knowledge’, which can only be communicated by observing the practical results of what other people do and imitating successful role models even when the ‘reasons’ for this success cannot be articulated verbally. For such knowledge to be transmitted it is imperative that there is a wide range of ‘experiments in living’ – whether in the production or consumption of goods – on which people can draw. The spread of knowledge in markets, the arts and science does not typically proceed via collective deliberation, but advances best when individuals and groups have a ‘private sphere’ that secures the freedom to experiment with projects that do not conform to majority opinions. Then, incrementally, through a process of emulation the prevailing wisdom may change over time. It is not sufficient for people to be able to talk about their ideas. Rather, they must have scope to act on those ideas – and this requires ‘property rights’, not ‘speech rights’. To restrict private property and the right of exit in favour of collective decisions is to reduce the total number of decisions made and hence limits the range of practical, lived experience from which we may all learn.
