A common characteristic of Humans is to see events through the lens of yesterday.
To see events in the way that makes THEMselves look good (or not bad)
To see events in a way that makes THEIR situation/world-view/ previously expounded positions improve/come to fruition
It is very common for Humans to not-wish to change their views or methods – and the longer they have held the view AND/OR the more “esteemed as an Expert” a person might be the desire to not-change grows stronger still

CONCLUDING NOTES ON THE SOCIAL PHILOSOPHY TOWARDS
WHICH THE GENERAL THEORY MIGHT LEAD
Is the fulfilment of these ideas a visionary hope? Have they insufficient roots in the
motives which govern the evolution of political society? Are the interests which they will thwart stronger and more obvious than those which they will serve?
I do not attempt an answer in this place. It would need a volume of a different character from this one to indicate even in outline the practical measures in which they might be gradually clothed.
But if the ideas are correct—an hypothesis on which the author himself must necessarily base what he writes—it would be a mistake, I predict, to dispute their potency over a period of time. At the present moment people are unusually expectant of a more fundamental diagnosis; more particularly ready to receive it; eager to try it out, if it should be even plausible.
But apart from this contemporary mood, the ideas of economists and political philosophers, both when they are right and when they are wrong, are more powerful than is commonly understood. Indeed the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually the slaves of some defunct economist. Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back.
I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas. Not, indeed, immediately, but after a certain interval; for in the field of economic and political philosophy there are not many who are influenced by new theories after they are twenty-five or thirty years of age, so that the ideas which civil servants and politicians and even agitators apply to current events are not likely to be the newest. But, soon or late, it is ideas, not vested interests, which are dangerous for good or evil.
All truth passes through three stages.
First, it is ridiculed.
Second, it is violently opposed.
Third, it is accepted as being self-evident.
