“The acceleration of the number of traders buying into the market in the inflating bubble captures the oft-quoted observation that bubbles are times when the "greater fool theory" applies.”

“The vacua with positive cosmological constant trap the universe in eternal inflation. They decay only locally, by producing bubbles of new vacua. Thus, every vacuum in the landscape will be realized an infinite number of times in different, causally disconnected regions. Each bubble expands to become an infinite open universe embedded in the global spacetime.”

“Stock market bubbles don't grow out of thin air. They have a solid basis in reality — but reality as distorted by a misconception.”

George Soros (1930) Hungarian-American business magnate, investor, and philanthropist

BuzzFlash interview (2004)
Context: Stock market bubbles don't grow out of thin air. They have a solid basis in reality — but reality as distorted by a misconception. Under normal conditions misconceptions are self-correcting, and the markets tend toward some kind of equilibrium. Occasionally, a misconception is reinforced by a trend prevailing in reality, and that is when a boom-bust process gets under way. Eventually the gap between reality and its false interpretation becomes unsustainable, and the bubble bursts.

“Water and a bubble on it are one and the same. The bubble has its birth in the water, floats on it, and is ultimately resolved into it.”

Ramakrishna (1836–1886) Indian mystic and religious preacher

Source: Sayings of Sri Ramakrishna (1960), p. 22
Context: Water and a bubble on it are one and the same. The bubble has its birth in the water, floats on it, and is ultimately resolved into it. So also the Jivatman (individual soul) and the Paramatman (supreme soul) are one and the same, the difference between them being only one of degree. For, one is finite and limited while the other is infinite; one is dependent while the other is independent.

“The most serious problems lie in the financial sphere, where the economy’s debt overhead has grown more rapidly than the ‘real’ economy’s ability to carry this debt. … The essence of the global financial bubble is that savings are diverted to inflate the stock market, bond market and real estate prices rather than to build new factories and employ more labor.”

“They were exciting times that bubbled over with energy for all those involved.”

The New York Times interview (1994)
Context: I've been very fortunate throughout my career. And I've been lucky enough to have worked with some great and talented people, like Price and Serling. I was just a part of the whole phenomenon coming together. They were exciting times that bubbled over with energy for all those involved.
