I picked up King of the Castle by Gai Eaton (1990) largely by accident. I saw someone reading the book on a flight; both the author and the book brief sounded unique, so I ordered a copy. A few quotes:
"Since unbelief lies at the root of almost all that is said or thought or done in our time, it follows that the believer's critique of the modern world cannot be less than radical." (p. 18)
"Before our eyes in the course of decades, not centuries, a new kind of world is coming into being, a world populated almost exclusively by dependants; but dependent upon whom and with what safeguards? Whether those who control the machinery of the State, the leaders in one country or another, have seized power or been elected by a mass-electorate which votes only on immediate, bread-and-butter issues, and whether they are motivated by self-interest or good intentions, one thing is sure: they are themselves controlled by forces of change which they do not understand and, in obeying these forces, they are restrained neither by immutable principles nor by the weight of custom and tradition. The brakes have been taken off; and there is nothing to suggest that these people know where they are going." (p. 60-61)
"The arrogance of the West in relation to other cultures is decently cloaked in our time, for this is an age of polite falsities; but it has not been outgrown. The fact that non-Europeans are expected to adopt Western patterns of government and 'post-Christian' morality (as enshrined in the Charter of the United Nations) is evidence of this." (p. 165)
"What the Muslims call the Holy War is in fact the opposition of the unified and God-centred man to the forces of dissipation and chaos both within and outside himself. Such warfare is likely, in our times, to provide a history of defeats and failures - at least so far as our environment taken as a whole is concerned - but this is precisely why we are told that less is expected of us than was expected of the men of earlier periods. Defeat does not matter, because it is by fighting this war that we become what we are, and the achievement of integrity is not dependent upon the quantitative and temporal outcome of that struggle. Our concern is only with doing what we are capable of doing. The rest is out of our hands." (p. 198)
