I recommend the series of essays by Smith, called From Optimism to Pessimism.
According to Spencer, most people are too ignorant to understand the detrimental long-term consequences of government intervention, so they will continue to embrace the superstition that a government can accomplish virtually anything, given the requisite political will and despite one failure after another. Experience counts for nothing here, because to understand the abstract nature of political institutions and their causal effects on social and economic interaction requires a level of conceptual ability that exceeds the intellectual powers of most people.
That quote is from Part 5 of the series. Another quote:
Spencer even criticized American democracy, because many Americans believed that “smart people” in government can do whatever they set out to do. Spencer, who was blunt if he was anything, was not reluctant to use words like “stupidity” when describing these and similar beliefs.
