- Chap 1) Common Sense. Both science and philosophy begin by aiming to explain the way things seem to be. Of course, the way things seem to be may turn out to be wrong. Nevertheless, it remains the natural starting point of inquiry. Theories are developed to explain why murder seems to be wrong, or why the sun seems to revolve around the earth.
- Chap 3) Disputing. Each theory tends to have both advocates and critics which dispute with each other to assess the relevant strengths and weaknesses of the particular theory. Both appeal to evidence to strengthen their theory, which tends to be intuitions in philosophy and observations in science. Both also appeal to counterevidence to weaken their opponent's theory, which tends to be intuitions or observations that contradict the theory. For example, utilitarians will point to utilitarianism's intuitive results (it is good to save someone's life because it maximises utility/happiness), while non-utilitarians will point to intuitions which contradict utilitarianism (it is wrong to kill an innocent person to save many others).
- Chap 5 & 6) Experiments & Comparing Theories. Counterevidence is discovered using experiments. Science generally uses natural experiments while philosophy generally uses thought experiments. Theories are then compared using the inference to the best explanation, which weighs the theoretical virtues of simplicity, coherence, and more, to decide between rival theories.
