A profusion of fancies and quotations is out of place in a love-letter. True feeling is always direct, and never deviates into by-ways to cull flowers of rhetoric. – Christian Nestell Bovee, Intuitions and Summaries of Thought: Vol.II, 1862

I am now to offer some thoughts upon that sameness or familiarity which we frequently find between passages in different authors without quotation. This may be one of three things either what is called Plagiarism, or Imitation, or Coincidence. – James Boswell, “The Hypochondriack,” No.XXII, 1779

Therein lies the marrow of the wisdom of the world. – Arthur Helps, “Chapter IV,” Companions of My Solitude, 1851
