Heresies

As far as I know at this moment, Chesterton wrote three main books about Christianity: 'Heretics', followed by 'Orthodoxy', and, years later, 'The everlasting man'. After reading the last two, I decided to start this blog. 'Heretics' is, however, the first written of the three; I recently started reading in it.
My first idea is that it has the form of a collection of essays, rather than of one sweeping argument. This is natural, since there are various different 'heresies' to discuss. Chapter one, however, is more general and begins with 'introductory remarks on the importance of orthodoxy'. Chesterton explains clearly why a man's philosophy is immensely important, that opportunism fails, and that he means, in this book, to go back to fundamentals.
Chapter two is also fairly general; here the difference between negative and positive ethics is explained. In the modern world, people tend to focus on the bad effects of doing wrong. While this is, of course, not wrong in itself, there is one thing missing: a sense of what is right, a sense of positive direction. The modern thinking will 'shirk the problem of what is good', but at the same time promote 'progress'. This thought is singular, for if we do not know the direction we should go, how can we make progress in this direction?
From chapter three on, Chesterton discusses particular cases, often using specific people to explain specific 'heresies'. For example, Rudyard Kipling is used as an example of how 'exploration and enlargement make the world smaller'. Becoming more global, we fail to understand the essence of a particular locality.
