A brilliant book of dialectical materialism. Although from the late revisionist Soviet Union, they are usually depending on the Author pretty good. You have to be careful. Alexander Spirkin seems to be one of these good Authors. You usually get the advantage of a deeper elaboration of dialectical materialism using the latest science. Which for this person, he knows an awful alot about the brain. Although I have some disagreements with how he phrases the consciousness question, generally he is correct and you'd have to know some pretty high level materialist theory of consciousness to be able to pick them out. And to be fair if I were to list all the positives compared to this minor negative. The positive would probably fill books of appraisal. If you want the "spiritual successor" to Anti-During, usually the late USSR books are pretty good at this.
It is very sad that these are not more widely known, deep thought out Marxist Materialist truths like consciousness is the function of the brain as highly organised matter (ie identical to it), are lost on most many modern Marxist, who are still lost in the field of Dualistic tendencies and an all to pervasive tendency to focus on the dialectic part of Dialectical Materialism. Consequently leading them to wholly negate the Materialist part, or even understand what mono-materialism or materialism is etc and revert to idealist Hegelian Dialectics. Anyway. This book does a long way of weeding out many errors in the conception of dialectical and historical materialism and is a master piece that everyone should read.
