In the preface to his book "Lectures On Partial Differential Equations" Arnold writes:

The effort to destroy this unnecessary scholastic pseudoscience is a natural and proper reaction of society) to the irresponsible and self-destructive aggressiveness of the super-pure mathematicians educated in the spirit of Hardy and Bourbaki.

I think this quote is very unfair towards Hardy. As far as I know he was not agressive and his book "Mathematician's Apology", it is written in a rather defensive manner. He writes his personal opinion about mathematics and never states that this is the only way that mathematics should be studied.

On the other hand there have been some Bourbakists who tried really agressively to enforce their opinion and style on all of mathematics.

Arnold didn't like Hardy, this is not a secret (for example, see this question https://hsm.stackexchange.com/questions/13614/does-arnold-say-that-hardy-is-responsible-for-ramanujans-untimely-death).

Question. Did Arnold really have any objective reason to put Hardy and Bourbakists on the same level? Or was this quote motivated by Arnold's personal dislike for Hardy?

Apology,Hardy had quite a few friends who thought kindly of him. Snow also says that Hardy was painfully shy, a condition that can be misread for arrogance. Hardy made his distaste for "applied" mathematics known, but expressed deep appreciation for mathematical physics. I believe I would have found Hardy outrageous but delightful. But, outspoken, opinionated people do tend to make enemies. Such is life. $\endgroup$2more comments
