本書研究了在西方文化語境下，“快樂”含義的演變，以及“快樂”這一情緒概念在文學、哲學創作中的運用。本書的研究時段為中世紀末至21世紀。作者蒂莫西·漢普頓（Timothy Hampton），美國加州大學伯克利分校多琳·湯森人文研究中心（Doreen B.Townsend Center for the Humanities）主任，著有《鮑勃·迪倫:歌曲如何起作用》《大使館小說:近代早期歐洲的文學與外交》。作者認為，從現代早期至當代，“快樂”是西方文學、哲學、藝術創作的重要主題，但因其具有的溫和屬性，一直以來都被文學和哲學研究者所忽略。這也構成了作者寫作的動機。作者在書中追溯了“快樂”的情感源流，追蹤了其在不同文體中的含義的變化——從宗教改革時期的新教神學評論，到現代美學，不一而足。作者以美國新冠疫情大流行時期作為全書的結束，再次強調了“快樂”是一種重要的情感力量，它所具有的至關重要的作用往往在危機時刻得以顯現。在災難的壓力下，“快樂”能讓人保持輕鬆的心態。 作者捕捉到了“快樂”這一轉瞬即逝的、強有力的、變革性的情感的眾多表象，系統地追溯了“快樂”的歷史和文學軌跡。

functions and Hecke L-functions of an imaginary quadratic field，and various problems on elliptic modular forms. As to the values of Dirichlet L-functions， all previous papers and books reiterate a single old result with a single old method. After a review ofelementary Fourier analysis， the author presents completely new results with new methods. though old results will also be proved. No advanced knowledge of number theory is required up to this point. As applications， new formulas for the second factor ofthe class number of a cyclotomic field will be given. The second half of the book assumes familiarity with basic knowledge ofmodular forms. However，all definitions and facts are clearly stated， and precise references are given. The notion ofnearly holomorphic modular forms is introduced and applied to the determination of the critical values of Hecke L-functions of an imaginary quadratic field. Other notable features of the book are： (1) some new results on classical E
