“I have misgivings about the term. “Spontaneous” can mean “impulsive” (as in “he spontaneously started dancing”), which is obviously unsuitable. In biology, it means “involuntary”, which also obviously doesn’t apply to human action. I suppose “without external cause” (as in “spontaneous combustion”) fits somewhat, because the direction of market activities occurs within the market and not outside of it.”
“But on the whole I think the term has the same problem as “emergent order”, “invisible hand” and “natural order”. They all make the social phenomena seem involuntary, either in a mystical or mechanistic way. And that is particularly unfitting for the Austrian tradition, which is distinguished for, more than any other tradition, consistently basing social science on purposive, deliberate, voluntary human action. I think “cooperative”, “polycentric”, or “distributed” order would be more accurate.”
There is a conception of “spontaneous order” or “emergent order” that is consistent with both Mises’s apriorism and the analytical aspect of Hayek’s thinking. Recall that Hayek provided his own conception of analytical social science:
“From the fact that whenever we interpret human action as in any sense purposive or meaningful, whether we do so in ordinary life or for the purposes of the social sciences, we have to define both the objects of human activity and the different kinds of actions themselves, not in physical terms but in terms of the opinions or intentions of the acting persons, there follow some very important consequences; namely, nothing less than that we can, from the concepts of the objects (X), analytically conclude something (Y) about what the actions will be. If we define an object in terms of a person’s attitude toward it (X), it follows, of course, that the definition of the object implies a statement about the attitude of the person toward the thing (Y). When we say that a person possesses food (X-1) or money (X-2), or that he utters a word (X-3), we imply that he knows that the first can be eaten (Y-1), that the second can be used to buy something with (Y-2), and that the third can be understood (Y-3)—and perhaps many other things.” (“The Facts of the Social Sciences”)
Here, Hayek provides his own conception of analytical social science, basically his own conception of praxeology.
If the above method is valid, then for any social object or phenomenon X which “appears” in action or in consciousness, its analytic corollary Y must also “spontaneously” appear. For any social object or phenomenon X which “appears” in action or in consciousness, its analytic corollary Y must “emerge” ordered with it.
In this conception, we assume that the social fact X which occurs for the actor is a fact of volition. For example, “I observe X” where “observation” is an intentional action. The (necessary) occurrence of Y we may conceive as the unintentional (i.e., “spontaneous”) result of the actor’s bringing about X. The actor brings about X (thus, purposive action). Y emerges “ordered” with X “spontaneously.”
Let’s look at Lionel Robbins’ conception of economic law:
“Economic laws describe inevitable implications. If the data they postulate are given, then the consequences they predict necessarily follow…If the “given situation” (X) conforms to a certain pattern, certain other features (Y) must also be present, for their presence is “deducible” from the pattern originally postulated.” (An Essay on the Nature & Significance of Economic Science)
Thus, any time we assume that social fact or social phenomenon X appears in the action or consciousness of the actor (any time we assume its “presence”), then social fact or social phenomenon__Y__ must also appear in the action or consciousness of the same actor, regardless whether the actor purposely aims for Y to appear. Social fact Y appears “spontaneously,” as it were, “ordered” with X, upon the appearance to the actor of social fact X.
The bridge that connects Misesian apriorism to Hayek’s spontaneous order is the conception of social fact X as the content of an intentional action, rather than as an objective fact of nature. This is where the mistake and oversight lies. Instead of conceiving that a market “exists” or a price “exists” in the objective sense, we can re-cast these social phenomena as contents of action by conceiving them as subjective facts: “I see a market” or “I observe a market” or “I’m visiting a market” etc… This re-casts the objective conception as a subjective action conception.
We have then satisfied Hayek’s objection to praxeology, which is:
“I have long felt that the concept of equilibrium itself and the methods which we employ in pure analysis have a clear meaning only when confined to the analysis of the action of a single person and that we are really passing into a different sphere and silently introducing a new element of altogether different character when we apply it to the explanation of the interactions of a number of different individuals.”
“…the sense in which we use the concept of equilibrium to describe the interdependence of the different actions of one person does not immediately admit of application to the relations between actions of different people.” (“Economics and Knowledge”)
Because we have now conceived social facts (prices, markets, interest rates, families, languages, laws, other people, etc.) as subjective phenomena (as the content of actions). Then Hayek’s analytical method (his own version of praxeology) must apply to these phenomena as social phenomena. When any of these social phenomena (X-1, X-2, X-3, etc.) “appear” to an actor as the content of his action (I observe X-1, I do X-2, I see X-3, etc.), then social phenomena Y-1, Y-2, and Y-3 must spontaneously “order” (i.e., spontaneously appear without any volition or conscious intention on the part of the actor) with X-1, X-2, and X-3 for that same actor. We may thus reconcile Misesian apriorism with Hayekian spontaneous order.
If I see a market, then by analytical necessity, exchange must “spontaneously” appear ordered with that market.
If I see a price, then by analytical necessity, selling must “spontaneously” appear ordered with that price.
If I hear a language, then by analytical necessity, communication must “spontaneously” appear ordered with that language.
