This is a well-known problem. Hypotheses must be continually verified anew by experience. In an experiment they can generally be subjected to a particular method of examination. Various hypotheses are linked together into a system, and everything is deduced that must logically follow from them. Then experiments are performed again and again to verify the hypotheses in question. One tests whether new experience conforms to the expectations required by the hypotheses. Two assumptions are necessary for these methods of verification: the possibility of controlling the conditions of the experiment, and the existence of experimentally discoverable constant relations whose magnitudes admit of numerical determination. If we wish to call a proposition of empirical science true (with whatever degree of certainty or probability an empirically derived proposition can have) when a change of the relevant conditions in all observed cases leads to the results we have been led to expect, then we may say that we possess the means of testing the truth of such propositions. With regard to historical experience, however, we find ourselves in an entirely different situation. Here we lack the possibility not only of performing a controlled experiment in order to observe the individual determinants of a change, but also of discovering numerical constants. We can observe and experience historical change only as the result of the combined action of a countless number of individual causes that we are unable to distinguish according to their magnitudes. We never find fixed relationships that are open to numerical calculation. The long cherished assumption that a proportional relationship, which could be expressed in an equation, exists between prices and the quantity of money has proved fallacious; and as a result the doctrine that knowledge of human action can be formulated in quantitative terms has lost its only support.

Because human beings are not falling stones, the methods of physics are a poor fit.
