I’m not trying to frighten you, but only a fool makes predictions based on ignorance; I am not that sort of fool.
We, practical revolutionaries, initiating our own struggle, simply fulfill laws foreseen by Marx, the scientist. We are simply adjusting ourselves to the predictions of the scientific Marx as we travel this road of rebellion, struggling against the old structure of power, supporting ourselves in the people for the destruction of this structure, and having the happiness of this people as the basis of our struggle.karl marx
I accept that climate change is a challenge, I accept the broad theory about global warming. I am sceptical about a lot of the more gloomy predictions.john howard
The usefulness of the models in constructing a testable theory of the process is severely limited by the quickly increasing number of parameters which must be estimated in order to compare the predictions of the models with empirical results.Anatol Rapoport
Nature has color-coded groups of individuals so that statistically reliable predictions of their adaptability to intellectual rewarding and effective lives can easily be made and profitably used by the pragmatic man-in-the street.william shockley
Four predictions of the Big Bang Theory have now been verified - surely enough to quench even the most biased critics.joseph silk
If there is a lesson in our story it is that the manipulation, according to strictly self-consistent rules, of a set of symbols representing one single aspect of the phenomena may produce correct, verifiable predictions, and yet completely ignore all other aspects whose ensemble constitutes reality...Arthur Koestler
Though he was proud of his scientific method, most of Marx' predictions are like Jewish prophecies and Christian revelations, inspiring, sometimes self-fulfilling, certainly true for the faithful, but not testable by scientific means.karl marx
Business success is less a function of grandiose predictions than it is a result of being able to respond rapidly to real changes as they occur.jack welch
Proof of Trotsky's farsightedness is that none of his predictions have come true yet.
The predictions of things to come relate to the state of the Church in all ages: and amongst the old Prophets, Daniel is most distinct in order of time, and easiest to be understood: and therefore in those things which relate to the last times, he must be made the key to the rest.
A comparative examination of the models of adaptive behavior employed in psychology (e.g., learning theories), and of the models of rational behavior employed in economics, shows that in almost all respects the latter postulate a much greater complexity in the choice mechanisms, and a much larger capacity in the organism for obtaining information and performing computations, than do the former. Moreover, in the limited range of situations where the predictions of the two theories have been compared (...), the learning theories appear to account for the observed behavior rather better than do the theories of rational behavior.
No physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics.
I believe Mahatma Gandhi was a futurist in the best sense of the word. He foresaw trends and had the confidence to record his predictions and prescriptions in bold and stark terms. He did so, not in a stray article or opinion piece, but over a life time of speeches, writings – and living – beginning with Hind Swaraj, the remarkable he started writing in 1909 and completed in 1910.
