Series “New Ideas in Philosophy” edited by N.O. Lossky and E.L. Radlova was first published in St. Petersburg by the Obrazovanie publishing house exactly one hundred years ago - in 1912-1914. In less than three years, seventeen collections were published. Among the authors of the articles are such well-known Russian and foreign scientists as A. Bergson, F. Brentano, W. Wundt, E. Hartmann, W. James, V. Dilthey, etc. Until now, the collections are a great bibliographic rarity and represent a huge educational and historical value primarily due to its content. In addition, over the past hundred years, neither individually nor, especially together, the collections have been published again.
