§ 2.

Difficulties may now and then occur in the performance of this process. We shall, perhaps, occasionally find ourselves unable to decide whether a given action does or does not trespass against the law of equal freedom. But such an admission by no means implies any defect in that law. It merely implies human incapacity—an incapacity which puts a limit to our discovery of physical as well as of moral truth. It is for instance, quite beyond the power of any mathematician to state in degrees and minutes, the angle at which a man may lean without falling. Not being able to find accurately the Edition: current; Page: [111] centre of gravity of a man’s body, he cannot say with certainty whether, at a given inclination, the line of direction will or will not fall outside the base. But we do not, therefore, take exception to the first principles of mechanics. We know that, in spite of our inability to follow out those first principles to all their consequences, the stability or instability of a man’s attitude might still be accurately determined by them, were our perceptions competent to take in all the conditions of such a problem. Similarly, it is argued that, although there may possibly arise out of the more complex social relationships, questions that are apparently not soluble by comparing the respective amounts of freedom the concerned parties assume, it must nevertheless be granted that, whether we see it or not, their claims are either equal or unequal, and the dependent actions right or wrong accordingly.
