""When Thomas Paine exclaimed: 'These are the times that try men's souls, '"" Rosenstock-Huessy noted, Paine ""did not mean men's bodies or men's minds. And we know it."" In this book devoted to knowledge of that mysterious entity, ""soul,"" which neither philosophers nor psychologists will have anything to do with, Rosenstock-Huessy gives soul essential, practical meaning. Without recourse to anything mystical or transcendental or merely poetic, he assures us of the reality of the individual soul for healthy human beings, and connects it to his larger work on an entirely new grammar that elevates to primacy the imperative and vocative forms of speech. Rosenstock-Huessy makes us aware, as few other writers can do, of the limitations inherent in the structure of the natural and social sciences, how much is blindly left out for the sake of adhering strictly to materialist and quantitative methods. In any lifetime there are profound transformations of one's soul, which a correct analysis of grammar, true to human experience, helps us recognize and appreciate. As he states here, ""The grammar of the soul is not an ineffectual luxury. . . . The disclosure of the miraculous world of the soul by a grammar based on the primal forms will create an applied study of the soul that should assume its place next to the modern era's technical natural science."" ""Rosenstock-Huessy was a prophet who, like many great prophets, failed in his own time, but whose time may now be coming."" --Harold J. Berman ""I was influenced enough by Rosenstock-Huessy to write a now forgotten book on his theme Respondeo etsi mutabor, 'I respond although I will be changed.' The motto would be on my coat-of-arms if I had one."" --Martin E. Marty ""Rosenstock-Huessy continually astonishes one by his dazzling and unique insights."" --W. H. Auden Eugen Rosenstock-Huessy (1888-1973) was a historian and social philosopher who, along with his friend Franz Rosenzweig, and Ferdinand Ebner and Martin Buber, was a major exponent of speech-thinking (sprachdenken). The central insight of speech-thinking is that speech or language is not merely, or even primarily, a descriptive act, but a responsive and creative act, which forms the basis of our social existence. The greater part of Rosenstock-Huessy's work was devoted to demonstrating how speech, as distinguished from mere chatter, through its unpredictable fecundity, expands our powers and unites humankind through time and space.
