The dialectical materialism of Marx is not only a useful philosophical method for understanding the processes of society, but is also a powerful tool for the assessment of the scientific method, according to Marxists Grant and Woods. . . . They explain the philosophical basis of dialectical materialism and defend its practice using examples from current work in formal logic and physics. They suggest that just as science provides confirmation of dialectical materialism, so dialectical materialism helps demonstrate where science has lost its way. They are especially critical of the injection of mysticism into current works of theoretical physics. Book News
