Jack Bogle founded Vanguard and is widely seen as the founder of the low-fee passive approach to investing. In this concise and clearly explained book he outlines his investment philosophy.

Instead of trying to find a fund that beats the market, which is like looking for a needle in a haystack, Bogle tells you to “buy the haystack”. Buying the entire market is now cheaper and easier than ever before, and more people are moving towards Bogle’s approach as investors lose faith in the ability of active managers to beat the market.
