I want to know the answer to the following question:
What theory was developed by Arnold?
All the background I'm provided with is that ": Classic and Contemporary Readings (Oxford, 2003); Peter Goldie (1946–2011), a British philosopher who specialized in ethics, aesthetics, emotion, mood and character; Nico Frijda (1927–2015), a Dutch psychologist who advanced the theory that human emotions serve to promote a tendency to undertake actions that are appropriate in the circumstances, detailed in his book The Emotions (1986).". Is that enough to answer the question?
Answer: no
