Quote by Bertrand Russell

It is not what the man of science believes that distinguishes him, but how and why he believes it. His beliefs are tentative, not dogmatic; they are based on evidence, not on authority or intuition.

Summary

This quote emphasizes that what sets apart a scientist is not simply what they believe, but rather the way they come to those beliefs. A scientist's belief system is not rigid and unquestionable, but rather flexible and open to change. Their beliefs are grounded in evidence and empirical observations, not solely on the opinions of authoritative figures or personal intuitions. By placing emphasis on rationality, evidence, and a willingness to question and adapt, this quote highlights the distinctive approach and mindset of a scientist.

Having learnt from experiment and argument that a stone falls downwards, a man indubitably believes this, and always expects the law he has learnt to be fulfilled.But learning just as certainly that his will is subject to laws, he does not and cannot believe it.However often experiment and reasoning may show a man that under the same conditions and with the same character he will do the same thing as before, yet when, under the same conditions and with the same character, he approaches for the thousandth time the action that always ends in the same way, he feels as certainly convinced as before the experiment that he can act as he pleases. Every man, savage or sage, however incontestably reason and experiment may prove to him that it is impossible to imagine two different courses of action in precisely the same conditions, feels that without this irrational conception (which constitutes the essence of freedom) he cannot imagine life. He feels that, however impossible it may be, it is so, for without this conceptions of freedom not only would he be unable to understand life, but he would be unable to live for a single moment.He could not live, because all man's efforts, all his impulses to life, are only efforts to increase freedom. Wealth and poverty, fame and obscurity, power and subordination, strength and weakness, health and disease, culture and ignorance, work and leisure, repletion and hunger, virtue and vice, are only greater or lesser degrees of freedom.A man having no freedom cannot be conceived of except as deprived of life.If the conception of freedom appears to reason a senseless contradiction, like the possibility of performing two actions at one and the same instant of time, or of an effect without a cause, that only proves that consciousness is not subject to reason.
