Schopenhauer argues that the empirical world exists only as a representation: 'every object, whatever its origin, is, as object, already conditioned by the subject, and thus is essentially only the subject's representation.' A representation is a subjective state that has been ordered according to space, time and causality - the primary forms of sensibility and understanding. So long as we turn our thoughts towards the natural world, and search for the thing-in-itself behind the representation is futile. Every argument and every experience leads only to the same end: the system of representations, standing like a veil between the subject and the thing-in-itself. No scientific investigation can penetrate the veil; and yet it is only a veil, Schopenhauer affirms, a tissue of illusions which we can, if we choose, penetrate by other means. The way to penetrate the veil was stumbled upon by Kant.

An international socialism is the stated ideal of most socialists; an international liberalism is the unstated tendency of the liberal. To neither system is it thinkable that men live, not by universal aspirations but by local attachments; not by a "solidarity" that stretches across the globe from end to end, but by obligations that are understood in terms which separate men from most of their fellows-in terms such as national history, religion, language, and the customs that provide the basis of legitimacy.

Of course, there are those - Sandel, Walzer and Dworkin, for example - who propose "communitarian" ways of thinking, as a further move in the direction which a sophisticated liberalism requires. But none of them is prepared to accept the real price of community: which is sanctity, intolerance, exclusion, and a sense that life's meaning depends upon obedience, and also on vigilance against the enemy.

A developed legal system, with elaborate common law rights, and supported by a system of natural justice, was the most precious legacy of our empire. If it were still permissible to defend colonization, I should justify it in terms of this bequest, and at the same time contrast the colonization of Africa with the Soviet "colonization" of eastern Europe, which has advanced not by the generation but by the destruction of law.

It goes without saying that apartheid is offensive. It was adopted, however, as the lesser of two evils. The Afrikaners believe that black majority rule has, in almost every case, led to the collapse of the constitutional government which they brought to South Africa, and upon which their freedoms and privileges - and perhaps even their lives - depend. And it did not seem so very bad to deny to blacks a vote which they would, when in power, promptly deny to themselves.
