In May 1906, the Atlantic Monthly commented that Americans live not merely in an age of things, but under the tyranny of them, and that in our relentless effort to sell, purchase, and accumulate things, we do not possess them as much as they possess us. For Bill Brown, the tale of that possession is something stranger than the history of a culture of consumption. It is the story of Americans using things to think about themselves.
Brown’s captivating new study explores the roots of modern America’s fascination with things and the problem that objects posed for American literature at the turn of the century. This was an era when the invention, production, distribution, and consumption of things suddenly came to define a national culture. Brown shows how crucial novels of the time made things not a solution to problems, but problems in their own right. Writers such as Mark Twain, Frank Norris, Sarah Orne Jewett, and Henry James ask why and how we use objects to make meaning, to make or remake ourselves, to organize our anxieties and affections, to sublimate our fears, and to shape our wildest dreams. Offering a remarkably new way to think about materialism, A Sense of Things will be essential reading for anyone interested in American literature and culture.

در ماه مه 1906 ، ماهنامه آتلانتیک اظهار داشت که آمریکایی ها نه فقط در دوره ای از چیزها زندگی می کنند ، بلکه تحت استبداد آنها زندگی می کنند ، و ما در تلاش بی وقفه خود برای خرید ، خرید و جمع آوری چیزها ، آنها را به اندازه آنها در اختیار نداریم. ما را تصاحب کنید. از نظر بیل براون ، داستان این مالکیت چیزی غریب تر از تاریخ فرهنگ مصرف است. این داستان آمریکایی ها است که از چیزهایی برای فکر کردن در مورد خودشان استفاده می کنند.
مطالعه جدید جذاب براون ، ریشه های شیفتگی آمریکای مدرن به چیزها و مشکلی را که اشیا at در اواخر قرن برای ادبیات آمریکا ایجاد می کردند ، کشف می کند. این دورانی بود که ناگهان اختراع ، تولید ، توزیع و مصرف چیزها تعریف فرهنگ ملی را آغاز کرد. براون نشان می دهد که چگونه رمان های مهم آن زمان باعث شده اند که مسائل نه یک راه حل برای مشکلات ، بلکه مشکلات در نوع خود باشد. نویسندگانی مانند مارک تواین ، فرانک نوریس ، سارا اورن جیوت و هنری جیمز می پرسند که چرا و چگونه ما از اشیا to برای معنا سازی ، ساختن یا بازسازی خود ، سازماندهی اضطراب و عواطف خود ، متعالی ساختن ترس و شکل دادن به وحشی ترین حالت خود استفاده می کنیم رویاها ارائه یک روش کاملاً جدید برای تفکر در مورد ماتریالیسم ، کتاب “حس چیزها” برای هر کس که به ادبیات و فرهنگ آمریکایی علاقه مند است ، مطالعه اساسی خواهد بود.
