The greatest economic treatise ever written by an American.
— Michael Kinsley, describing Progress & Poverty in the Wall Street Journal, March 5, 1987
I have already read Henry George’s great book and really learnt a great deal from it. Yesterday evening I read with admiration — the address about Moses. Men like Henry George are rare, unfortunately. One cannot imagine a more beautiful combination of intellectual keenness, artistic form, and fervent love of justice.
— Albert Einstein
The economic premises of Henry George cannot be successfully challenged; they are based on common observation and knowledge. . .Henry George was a great economist— the first to look for causes of poverty and the first to find the major cause— but Henry George was much more than an economist. He was a philosopher, a complete humanitarian, an incorruptible personality, an idealist who believed in man’s personal and social capacity for infinite improvement and he was a prophet of the same class as the prophets of old in the Holy Scriptures.
— Preston Bradley, “Henry George, Biblical Morality and Economic Ethics” in American Journal of Economics and Sociology, July, 1980.
People do not argue with the teaching of [Henry] George, they simply do not know it. And it is impossible to do otherwise with his teaching, for he who becomes acquainted with it cannot but agree.
Henry George is one of the great names among the world’s social philosophers. It would require less than the fingers of the two hands to enumerate those who, from Plato down, rank with him. … [N]o graduate of a higher educational institution has a right to regard himself as educated in social thought unless he has some firsthand acquaintance with the theoretical contribution of this great American thinker.
— John Dewey
Politicians are urgently looking for believable, just, and practical methods of taxation. This is exactly what Henry George offers.
— John D. Davies, Bishop of Shrewsbury (from the foreword to From Wasteland to Promised Land)
Any one who really fears a revolution in America ought to reread Henry George’s “Progress and Poverty,” one of the great social documents of all time. I first read it thirty years ago. …Today the book is good as ever, and the theory as sane. … In all the years — with the travel, study, opportunity for observation of social conditions — in all these yers I have never known his premises to be shaken in the least.
"The history of mankind everywhere shows the power that special interests, capable of organization and action, may exert in securing the acceptance of the most monstrous doctrines."
- Henry George
