G. K. Chesterton 
Orthodoxy [EPUB ebook] 

Chesterton capped his brilliant literary career with this exploration of ‘right thinking, ‘ and how it led to his acceptance of the Christian faith. Although this is a very personal account of his conversion, Chesterton makes it clear he came to a rational decision based upon his scholarly examination of Christianity’s arguments, intending to provide a ‘positive’ companion to the previous Heretics.
