## Core Philosophy

Bogle viewed simplicity as the key to success, stating that discovering "the priceless jewels of simplicity" often requires cutting through a "swath of complexity." [Source: https://johncbogle.com/speeches/JCB_Morningstar_6-02.pdf] He believed that reversion to the mean is a "pervasive law of gravity" in financial markets. [Source: https://johncbogle.com/speeches/JCB_Morningstar_6-02.pdf] He urged investors to respect the power of reversion to the mean. [Source: https://johncbogle.com/speeches/JCB_Morningstar_6-02.pdf] He cautioned that compilations of historical financial market returns are not actuarial tables and that the past is usually "anti-prologue." [Source: https://johncbogle.com/speeches/JCB_Morningstar_6-02.pdf] He warned investors not to give way to a bull market atmosphere and become infected with enthusiasm and greed, nor to give way to a bear market atmosphere and become infected with negativism and fear. [Source: https://johncbogle.com/speeches/JCB_Morningstar_6-02.pdf] He counseled that success depends on realizing at the heights of ebullience and the depths of despair alike that "This too shall pass away." [Source: https://johncbogle.com/speeches/JCB_Morningstar_6-02.pdf] Bogle advocated "staying the course" by buying something solid and well diversified and holding it forever to enjoy the miracle of compounding returns without it being eaten away by the tyranny of investment costs. [Source: https://boglecenter.net/2018/09/30/bogleheads-on-investing-episode-001-transcript] He emphasized that "costs matter. Performance comes and goes, costs go on forever." [Source: https://boglecenter.net/2018/09/30/bogleheads-on-investing-episode-001-transcript] He embraced "candor as a marketing strategy," accepting that indexing means getting market returns whether those returns are good or bad. [Source: https://www.aqr.com/-/media/AQR/Documents/Insights/Interviews/Words-From-the-Wise-Jack-Bogle-on-Building-a-Better-Investment-Industry.pdf] He urged graduates to heed the definition of a true professional as one who "will create value for society, rather than extract it." [Source: https://jamesclear.com/great-speeches/enough-by-john-c-bogle] He warned that the more our financial system takes, the less our investors make. [Source: https://jamesclear.com/great-speeches/enough-by-john-c-bogle] He closed by stating that the great game of life is not about money; it is about doing your best to build the world anew.

[Source: https://johncbogle.com/speeches/JCB_Morningstar_6-02.pdf] In 1977, he eliminated Vanguard's load and abandoned its broker-dealer marketing system when he realized it did not make sense to be the low-cost provider and still have a substantial sales charge. [Source: https://www.aqr.com/-/media/AQR/Documents/Insights/Interviews/Words-From-the-Wise-Jack-Bogle-on-Building-a-Better-Investment-Industry.pdf] He favored funds with high "relative predictability" over those chasing concentrated bets. [Source: https://www.aqr.com/-/media/AQR/Documents/Insights/Interviews/Words-From-the-Wise-Jack-Bogle-on-Building-a-Better-Investment-Industry.pdf] His prescription for most investors was inaction: "don't do anything; just stand there" and "stay the course."
