To a person of analytical ability, perceptive enough to realise that mathematical equipment was a powerful sword in economics, the world of economics was his or her oyster in 1935. The terrain was strewn with beautiful theorems begging to be picked up and arranged in unified order.

Interpretation
What this quote means
The quote highlights the limitations of both Keynesian and neoclassical economics in addressing stagflation.
