How can the truth prevail? The answer (which gives some ground for hope) is that people interested in ideas, and prepared to think them through and express them regardless of personal disadvantage, have always been few; and if knowledge could not advance without a majority on the right side, there would never have been any progress at all – because it has always been easier to get into the limelight, as well as to make money, by charlatanry, doctrinarism, sycophancy and soothing or stirring oratory than by logical and fearless thinking. No, the reason why human understanding has been able to advance in the past, and may do so in the future, is that true insights are cumulative and retain their value regardless of what happens to their discoverers; while fads and stunts may bring an immediate profit to the impresarios, but lead nowhere in the long run, cancel each other out, and are dropped as soon as their promoters are no longer there (or have lost the power) to direct the show. Anyway, let us not despair.
