The background that Schwartz provides in Chapter 1 of his book actually illuminates Keynes’s own early philosophical ideas and the context of Keynes’s famous A Treatise on Probability (1921). I sketch the main points of Chapter 1 from Schwartz’s study in what follows.
Bertrand Russell (1872–1970) was the founder of analytic philosophy, but he drew on important work in mathematical logic by the German Gottlob Frege (1848–1925).
Russell and George E. Moore (1873–1958), another founder of analytic philosophy, attended Cambridge University in the 1890s, and came under the influence of British Hegelian philosophers.
Russell went through a number of philosophical phases as follows:
(1) a period of influence from British idealism;When Moore and Russell broke with Idealism, they had a brief flirtation with Platonic realism (Schwartz 2012: 28), and then Russell moved towards “logical atomism,” which is recognisably an early form of analytic philosophy.
(2) a period of Platonist realism (1901–1904);
(3) the period of logical realism (1905–1912), and
(4) the period of logical atomism (1913–1918).
In 1903, two important books appeared. Both of these works profoundly influenced the young John Maynard Keynes. The first (and most important to Keynes) was Moore’s Principia Ethica, an influential treatise on ethics; the second was Russell’s Principles of Mathematics (1903) (written in the latter’s Platonic realist phase).
Russell’s book was concerned with the foundations of mathematics, and in it Russell argued that mathematics could be deduced from a very small number of principles, a view which is the hallmark of the philosophy of mathematics called logicism.
But the ground for Russell’s logicist interpretation of mathematics had already been laid by Gottlob Frege in his Begriffsschrift (1879), Die Grundlagen der Arithmetik (The Foundations of Arithmetic; 1884), and the Grundgesetze der Arithmetik (Basic Laws of Arithmetic; vol. 1: 1893; vol. 2: 1903), in which works Frege founded modern logic and argued against Kant’s view that arithmetic statements were synthetic a priori knowledge. Against this Kantian view, Frege held that arithmetic was analytic a priori, and tried to demonstrate how a new logic could be used to deduce mathematics from a set of given axioms.
Russell’s early work uncovered a flaw in Frege’s system called Russell’s paradox, but Russell continued his work in the 1900s in an attempt to solve this paradox and complete Frege’s vision.
Russell and Alfred North Whitehead (1861–1947) worked on the culmination of their logicist program in mathematics, the three-volume book Principia Mathematica (the volumes of which were published in 1910, 1912, and 1913 respectively). In the Principia Mathematica, Russell and Whitehead attempted to construct a set of axioms and rules by means of symbolic logic from which all mathematics could be proven.
Though it is generally thought that Russell’s strict logicist program failed (given the problems raised by Gödel’s incompleteness theorems), nevertheless the consensus today is still that most of classical mathematics can be derived from pure logic and set theory (Schwartz 2012: 19), so in one important respect the essence of Russell’s logicist program was successful.
Thus the main legacy of Russell’s logicism was the rejection of Kantian synthetic a priori knowledge. For after it was shown that mathematics was not an example of synthetic a priori knowledge, one of the greatest arguments made by Rationalist apriorists was undercut and refuted.
Another influence that Russell’s logicism had was on John Maynard Keynes. Keynes’s own “logical theory of probability” was itself a logicist attempt to put probability and inductive inference on a sound footing by using a system of formal logic (Gillies 2000: 27). It is notable that Russell himself was deeply involved in helping Keynes with his work on probability (Gillies 2000: 27), although the initial inspiration for Keynes’s work on probability came from Moore’s Principia Ethica (Gillies 2000: 28).
The other major philosophical achievement of Russell covered by Schwartz is Russell’s article “On Denoting” (Mind 14 [1905]: 479–493), a landmark in the analytic philosophy of language. In this, Russell developed a theory of “definite descriptions,” or phrases that pick out one specific object, such as the “30th Prime Minister of the United Kingdom” or “my copy of Keynes’s General Theory.” These are distinguished from proper names, and philosophical problems arise when definite descriptions refer to non-existent objects, such as “the present king of France” or the “current president of Canada,” and propositions such as “the present king of France is bald.”
For Russell, these “definite description” propositions were merely informal ways of expressing existential statements: for example, the proposition “the present king of France is bald” is really to be understood as “there is one and only one present king of France and that one is bald” (Schwartz 2012: 24). Such existential statements are clearly false in terms of their truth value, so that Russell was able to reject the questionable theory of definite descriptions developed by Meinong (Schwartz 2012: 23).
By the time Russell turned to actual philosophy in the 1910s, he continued the British empiricist tradition of Locke, Berkeley and Hume (Schwartz 2012: 34), and modern analytic philosophy, for better or worse, has continued largely to shun both Hegelianism and modern Continental philosophy.

It has also continued to shun -- and this is perhaps the most important point -- the work of George Berkeley upon whose work the entire project is based. I've said this before, but it bears repeating: Hume's philosophical project developed out of Berkeley's criticism of Universals in which he made the point that all Universals are really just Particulars.
ReplyDeletehttp://en.wikipedia.org/wiki/Problem_of_universals#Berkeley
Of course this argument was quite explicitly used to undermine the project of Enlightenment, at that time generally associated with Newton (who, of course, was busy undermining Enlightenment in his own way through his private alchemical studies [which Keynes would go on to salvage despite most Newtonians wanting them burned]). But Hume just raided (or misunderstood) Berkeley's criticism and began the contemporary project of Enlightenment thought as we know it today.
A sad history, really.
"Hume's philosophical project developed out of Berkeley's criticism of Universals in which he made the point that all Universals are really just Particulars."
DeleteDoes the argument for the existence of an external reality collapse if one accepts extreme nominalism with respect to universals? I'm not quite sure I follow here.
I think the consensus is that it does, yes. In Hume there is no guarantee for reality. Hence his skepticism. Then Kant "saves" it by putting the a prioris in place.
DeleteThere's a big problem with that.
One of Berkeley's most searing criticisms -- which can be found in The Analyst -- is that abstract ideas like the a prioris ultimately require some sort of belief. Since they do not exist as particulars we cannot conceive of them in any meaningful way. Thus we must believe in them (the famous example is that of the "first differences" of Newton's calculus). But, Berkeley says, this is no different from believing in God. In the same way as we cannot conceive of a prioris or first differences we can't conceive of God either. So, there's no difference in belief in God or in belief in a prioris etc. That, to me, is a perfectly coherent argument and an extremely damning one.
"Subjective Idealism (immaterialism or phenomenalism) describes a relationship between experience and the world in which objects are no more than collections or "bundles" of sense data in the perceiver. Proponents include Berkeley, Bishop of Cloyne, an Irish philosopher who advanced a theory he called immaterialism, later referred to as "subjective idealism", contending that individuals can only know sensations and ideas of objects directly, not abstractions such as "matter", and that ideas also depend upon being perceived for their very existence - esse est percipi; "to be is to be perceived".
DeleteArthur Collier published similar assertions though there seems to have been no influence between the two contemporary writers. The only knowable reality is the represented image of an external object. Matter as a cause of that image, is unthinkable and therefore nothing to us. An external world as absolute matter unrelated to an observer does not exist as far as we are concerned. "
http://en.wikipedia.org/wiki/Idealism#Subjective_idealism
It's unclear to me, but did Berkeley deny the existence of any material external world whatsoever? Or was he saying maybe it does exist but is "nothing to us"?
Yes. For Berkeley there is no "external world". Just sensations, perceptions and ideas. The only thing that guarantees objectivity and truth for Berkeley is therefore existence of God.
DeleteThink of the old "If a tree falls in the woods does it make a noise if no one is around to hear it?". Berkeley would say "No, not unless you believe that God is there to hear it". Thus objective truth can only be registered, for Berkeley, if one supposes the existence of God.
To me this is a far more profound point than Kant's a priori stuff. In reality, Kant is just creating deities and not calling them such. We cannot actually conceive of an a priori any more than we can conceive of a triangle as a General entity. The difference being that we don't even encounter Particular a prioris while we do encounter Particular triangles. This means that the a priori has the EXACT same ontological structure as the idea of God. It is a General for which there is no Particular yet we believe in it regardless.
I would imagine Berkeley would admit that he was hinting that such was the worship of false idols, if you had pushed him on the point.
Out of curiosity Lord Keynes, did you read either of these two papers? They might prove to be of some use to your interest in philosophy.
