Science teaches thinking

The idea of the outward-looking, self-transcending stance expressed itself in two connected ways for Russell. One related to science, the other to personal relationships and the individual’s attitude to others in general. In regard to science, the objectivity and scope of science is obviously such as to make individual self-concern a very minor if not indeed nugatory thing. In the essay ‘The Place of Science in a Liberal Education’ Russell worte, ‘The kernel of the scientific outlook is the refusal to regard our own desires and interest as affording the key to the understanding of the world’, and this immediately entails that the disciplines of reason and evidence are the sole legitimate determinants of thinking in general. [69-70]

The right not to tolerate the intolerant

Less well known is the paradox of tolerance: Unlimited tolerance must lead to the disappearance of tolerance. If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them.—In this formulation, I do not imply, for instance, that we should always suppress the utterance of intolerant philosophies; as long as we can counter them by rational argument and keep them in check by public opinion, suppression would certainly be unwise. But we should claim the right to suppress them if necessary even by force; for it may easily turn out that they are not prepared to meet us on the level of rational argument, but begin by denouncing all argument; they may forbid their followers to listen to rational argument, because it is deceptive, and teach them to answer arguments by the use of their fists or pistols. We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant. We should claim that any movement preaching intolerance places itself outside the law, and we should consider incitement to intolerance and persecution as criminal, in the same way as we should consider incitement to murder, or to kidnapping, or to the revival of the slave trade, as criminal. [ch. 7, n4]

Imagination and criticism in science

Diese spekualtiven Welten sind, wie in der Kunst, Produkte unserer Phantasie, unserer Intuition. Aber in der Wissen­schaft werden sie von der Kritik kontrolliert: Die wissenschaftliche Kritik, die rationale Kritik, ist von der regulativen Idee der Wahrheit geleitet. Wir können unsere wissenschaftlichen Theorien niemals recht­fertigen, denn wir können nie wissen, ob sie sich nicht als falsch herausstellen werden. Aber wir können sie kritisch überprüfen: An die Stelle der Rechtfertigung tritt die rationale Kritik. Die Kritik zügelt die Phantasie, ohne sie zu fesseln. [67]

How to choose and evaluate our politicians

I think the first thing, in a democracy, where there is at least some pretense about the people controlling government policy, is that every democratic process ought to be used. You can make sure that those whom you vote for have rational views on these matters. You can work hard to make sure that there is a real difference of opinion in the alternative candidates. You can write letters to newspapers and so on. But more important than any of that, I believe, is that each of us must equip him- or herself with a “baloney-detection kit.” [257]

When can an opinion be relied on?

There is the greatest difference between presuming an opinion to be true, because, with every opportunity for con­testing it, it has not been refuted, and assuming its truth for the purpose of not permitting its refutation. Complete liberty of contradicting and disproving our opinion, is the very condition which justifies us in assuming its truth for purposes of action; and on no other terms can a being with human faculties have any rational assurance of being right. [ch. II, 26]

The enemy of truth and rationality

Es gibt ein totales Engagement, das die unvoreingenommene Wahrheitssuche und das kritisch-rationale Denken beseitigt oder zumindest beeinträchtigt und das im Endeffekt – gleichgültig, ob es im Namen des Glaubens und einer göttlichen Macht, im Namen der Geschichte oder in dem der Vernunft in Erscheinung tritt – immer wieder zu totalitären Konsequenzen geführt hat. […] Es kommt hier vielmehr darauf an, daß unter gewissen strukturellen Gesichtspunkten Katholizismus, Kalvinismus, Kommunismus und Faschismus zusammengehören, nicht etwa, weil alle diese historisch sehr komplexen Phänomene in jeder Hinsicht gleichartig oder auch nur gleichwertig wären, sondern weil in ihnen das extreme Gegenteil der im analytischen Denken postulierten Neutralität wirksam war oder ist: die blinde Parteilichkeit, der gehorsame Glaube, das unkorrigierbare Engagement. [5-6]

Science, Philosophy, and Method

And yet, I am quite ready to admit that there is a method which might be described as ‘the one method of philosophy’. But it is not characteristic of philosophy alone; it is, rather, the one method of all rational discussion, and therefore of the natural sciences as well as of philosophy. The method I have in mind is that of stating one’s problem clearly and of examining its various proposed solutions critically.

I have italicized the words ‘rational discussion’ and ‘critically’ in order to stress that I equate the rational attitude and the critical attitude. The point is that, whenever we propose a solution to a problem, we ought to try as hard as we can to overthrow our solution, rather than defend it. Few of us, unfortunately, practise this precept; but other people, fortunately, will supply the criticism for us if we fail to supply it ourselves. Yet criticism will be fruitful only if we state our problem as clearly as we can and put our solution in a sufficiently definite form—a form in which it can be critically discussed.

I do not deny that something which may be called ‘logical analysis’ can play a role in this process of clarifying and scrutinizing our problems and our proposed solutions; and I do not assert that the methods of ‘logical analysis’ or ‘language analysis’ are necessarily useless. My thesis is, rather, that these methods are far from being the only ones which a philosopher can use with advantage, and that they are in no way characteristic of philosophy. They are no more characteristic of philosophy than of any other scientific or rational inquiry.

It may perhaps be asked what other ‘methods’ a philosopher might use. My answer is that though there are any number of different ‘methods’, I am really not interested in enumerating them. I do not care what methods a philosopher (or any­body else) may use so long as he has an interesting problem, and so long as he is sincerely trying to solve it. [xix-xx]

Pinker on Intelligence

Intelligence, then, is the ability to attain goals in the face of obstacles by means of decisions based on rational (truth-obeying) rules. The computer scientists Allen Newell and Herbert Simon fleshed this idea out further by noting that intelligence consists of specifying a goal, assessing the current situation to see how it differs from the goal, and applying a set of operations that reduce the difference. Perhaps reassuringly, by this definition human beings, not just aliens, are intelligent. We have desires, and we pursue them using beliefs, which, when all goes well, are at least approximately or probabilistically true. [62]
