An emphasis on the dialectical interaction between science and nature brings out ways in which Natura as an actress resists and reacts to Scientia's scientific and technological innovations. The inclusion of gender in investigations of science and nature, the fight against racism, and a renewed emphasis on economic equalities can move us all toward a more democratic future. The assumption that Science can know Nature has been made in Western culture over many years. The logical positivism of the Vienna Circle, during the first-half of the twentieth century, held that the only ways in which science could know nature were through two kinds of statements. Logical, including mathematical, statements were true by virtue of being tautologies, but needed empirical content to be scientific truths. Empirical statements were true be virtue of being testable through experimentation and observation. Together, the two types constituted scientific knowledge of the natural world.
