*The Philosophical Thought of Ayn Rand* is a collection of ten essays on Ayn Rand's philosophy of Objectivism, more or less hierarchically organized into three parts: Metaphysics and Epistemology, Ethics and Politics.
The essays included fall into two very distinct categories: those written by independent Ayn Rand scholars, like Den Uyl, Rasmussen, Machan or Mack, who show a real familiarity with Rand's published works (or, to be more precise, those works published prior to the publication of the book in 1984); and essays written by generally unsympathetic philosophers who merely took the trouble of reading a few Objectivist essays before refuting what are mostly misunderstandings of Rand's statements or arguments.
One example is Anthony Flew, whose pompously titled essay "Selfishness and the Unintended Consequences of Intended Action" combines a very cogent defense of the free market with a completely inept treatment of Rand's rational egoism. Flew takes the following statement from *The Fountainhead*: "No man can live for another... It is impossible in concept"; interprets it as meaning that no action can be unselfish and self-sacrificing; easily refutes the latter; and then blames Rand for her "false conclusion", her "lapse" and the "mess" she got herself into. Unfortunately for him, Rand was not saying that it is impossible ever to *act* in a self-sacrificial way, but that it was impossible consistently to *live* for another, which is totally different, and which I do not think Flew would be able to refute. As for his comment that "Rand is... mistaking it that all human relationships are or should be trading transactions", I surmise it is based on too literal an interpretation of the "trader principle", which is the Objectivist alternative to predatory egoism and altruism. Finally, the refutation of the Objectivist principle that there is no conflict of interest among rational men is based on an unjustified reading of "interest" as synonymous with "desire".
But the nadir of this collection is probably Wallace Matson's "Rand on Concepts" which claims to reformulate the Objectivist theory of concept-formation in a way that "preserves what is of value in Rand's treatment" and then proceeds to get rid of concepts altogether, claiming they are a dispensable "mysterious and subjective... third entity between word and thing"!
Of the ten essays included here, I would say that the five written by the better-informed Ayn Rand scholars are worth reading and often contain interesting observations and criticisms (though none that are so earth-shattering as to really threaten the structure of Objectivism), while the other five, when they are not off-topic, are generally lame.
