I'll start with a bold claim: If you want to understand the world better, then you should read this book. This is not, of course, to suggest that it has all of the answers about everything. Still, Tom Pepper's book "Indispensable Goods" does something fundamental: It gives us a chance to rethink the very questions we are asking about the world, to re-examine the assumptions these questions are based on.
Let me use an analogy to illustrate what such a shifting of assumptions can mean. Consider the paradigm shift in astronomy from the Ptolemaic geocentric system to the heliocentric system. Rather than trying to answer puzzling questions on the order of 'Why do planets move around the Earth in this complicated fashion involving epicycles?', "Indispensable Goods" asks us to consider that maybe this question is so hard to answer because it is based on a flawed premise and goes on to suggest another approach to the issue. The book does this for a variety of problems, including human nature, language, the mind, free will, reason, emotion, economics, and history. For example, Pepper presents Galen Strawson's "basic argument" against free will, which shows that the concept of free will does not make sense. As an alternative, Pepper suggests that human agency consists in our ability to improve our understanding of the world and adjust our actions based on this understanding.
However, returning to the analogy of astronomy from above, instead of providing a complete heliocentric theory, what Pepper does is more like presenting the idea that the planets revolve around the sun and briefly arguing that this conceptual approach is more promising. This has the drawback, of course, that after reading the book one will probably still have a lot of questions about the proposed alternatives. (I know I do.) It has the enormous advantage, though, that it allows "Indispensable Goods" to cover a lot of different areas (as mentioned above) in order to bring them together to form a coherent and convincing way of understanding the world and human life. (Each of the areas considered in "Indispensable Goods" would probably require a book of their own to be discussed in more satisfying detail and, indeed, "Indispensable Goods" contains many recommendations for further reading.)
The book's contents are not just an exercise so that we can feel smarter afterwards and go on as we were, though. (German philosopher Richard David Precht essentially suggests this is all philosophy can do in the introduction to "Erkenne die Welt", the first volume of his series of books on the history of philosophy.) But in order to understand what Pepper is trying to encourage us to do beyond understanding new concepts, we have to discuss the central aim of the book.
The reconsideration of a variety of concepts like human nature, language, the mind, free will, reason, etc. makes up most of the book (Chapters 4 to 13) and is fascinating by itself, but it serves another purpose: Tom Pepper sets out to explain Louis Althusser's theory of ideology. Ideology here, does not simply refer to a "false consciousness" or, to take two descriptions from the Online Etymology Dictionary, "a prescriptive doctrine that is not supported by rational argument", or a "systematic set of ideas, doctrines through which the world is interpreted". As Pepper explains, Althusser's concept of ideology has to do with the very way we collectively organize and live our lives. Perhaps this can be clarified a bit by contrasting ideology with science. Science, on this model, is our attempt to understand what the world is like, what things are real and how these things work. Ideology, on the other hand, consists of what we want to do in the world. Thus, ideology in this sense is something we, as human beings, cannot do without. This is surely a very inadequate description, but it should at least convey the significance that ideology has if Pepper and Althusser are correct.
So, how does this affect what we should do? Pepper's crucial contention is that we can - collectively - consciously choose our ideology and thereby improve our lives for the better. Now, it may seem at this point that we would not have any criteria for what 'better' might mean that do not depend on our current ideology. And, I suppose, this is true. However, if we accept as fundamental that it is a good thing to eliminate sources of human suffering, which is itself an ideological belief, then there is also an objective component to our choice of ideologies. This is so, according to Pepper, because some ideologies are better suited to fulfilling our human nature, which, as you may recall, is one of the concepts that is discussed in the book. And this really is the main goal of "Indispensable Goods": to encourage us to do something about human suffering - from obviously global issues like the hunger and poverty in the world or the threat of global warming to apparently individual issues like depression, addiction, or suicide - and explain how we may accomplish this.
So, what can we do to reduce human suffering? "Indispensable Goods" suggests a twofold anser to this question: critiquing existing ideologies and producing new ideologies based on the lessons learned from the critique. To this end, Pepper first outlines three basic forms of ideological critique at the end of Chapter 14. Then, in Chapter 15, he sketches what kind of practices could be employed to consciously produce new ideologies, using the example of community theater. More precisely, Pepper sketches here a production of Shakespeare's "Romeo and Juliet" based on the ideas of Bertolt Brecht's epic theater.
If the ideas presented in "Indispensable Goods" are true, then why are they not better known? Pepper attempts to answer this question in Chapters 2 and 3, discussing what he calls the 'ontological collapse' and the 'fear of sociality', respectively. Let me briefly try to explain roughly what these terms mean. Ontological collapse refers to the failure to take seriously both those parts of reality that exist independently of human activity and those parts which are socially constructed. In other words, it is the assumption that only one of these areas of reality, which Pepper calls 'mind-independent' and 'mind-dependent', can be really real. Instead, Pepper suggests that both are completely real, even though they are real in different ways. Fear of sociality, then, refers to the refusal to even consider the possibility that our identities and our very mind are socially constructed. Pepper argues that most of us today make these two errors, which prevent a correct understanding of the world, because they are implicit in the common sense assumptions we grow up with.
To be quite honest, after reading the book, rereading some sections and having read a few (though really just a small fraction) of the recommendations for further reading, I still feel like I do not understand many of the positions advanced in "Indispensable Goods" nearly as well as I would like. While the book itself is very accessible and engagingly written, really understanding what it says takes time and effort. However, this book also shows how enjoyable and satisfying rigorous thinking about the world can be. "Indispensable Goods" makes me really want to better understand the issues it discusses. And, as this review has hopefully made clear, these issues intimately concern all of our lives.
