"The suppression of uncomfortable ideas may be common in religion or in politics, but it is not the path to knowledge, and there is no place for the endeavor of science. We do not know beforehand hand where fundamental insights will arise from about our mysterious and lovely solar system, and the history of our study of the solar system shows clearly that accepted and conventional ideas are often wrong, and the fundamental insights can arise from the most unepected sources."
