There's nothing in Keynesian economics that would allow you to solve stagflation. But there's nothing in neoclassical economics that would allow you to solve stagflation, either.
Interpretation
The quote highlights the limitations of both Keynesian and neoclassical economics in addressing stagflation.
In this quote, Paul Samuelson emphasizes the challenges posed by stagflation, a situation characterized by stagnant economic growth and high inflation. He asserts that neither Keynesian economics, which focuses on total spending in the economy and its effects on output and inflation, nor neoclassical economics, which emphasizes free markets and the importance of supply and demand, provide effective solutions to this complex issue, indicating a significant gap in economic theories when faced with such phenomena.
In practice
In a lecture about economic theory, one could use this quote to illustrate the limitations of different economic frameworks.
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.
I can't think of a president who has been overburdened by a knowledge of economics.

I realized that the ordinary old-fashioned Euclidean geometry didn't apply.
Economics has never been a science - and it is even less now than a few years ago.
It has often been found that profuse expenditures, heavy taxation, absurd commercial restrictions, corrupt tribunals, disastrous wars, seditions, persecutions, conflagrations, inundation, have not been able to destroy capital so fast as the exertions of private citizens have been able to create it.
By a continuing process of inflation, government can confiscate, secretly and unobserved, an important part of the wealth of their citizens.
One of the most powerful insights in economics is this idea of a division of labor. You do the thing you're good at. Other people do something else that they're good at. The net effect is better for everybody.
You know, I think of the global economy as an inverted triangle, resting on the shoulders of the American consumer. And if the American consumer cannot have enough disposable income in order to maintain a standard of living that creates more opportunities generation after generation, that's bad for everybody.
Obama had to save the banks, sure, but he didn't have to save the bankers and the shareholders and the bondholders. We broke the rules of capitalism in order to save those at the top - as we always do.
Policy makers should be compelled to take action given the serious costs of long-term unemployment when overall unemployment is already high. A week of unemployment is worse when it is experienced as part of a longer spell.
