From Lawson Tait   25 February 1877

7, Gt. Charles Street, | Birmingham.

Feb 25/77

My Dear Sir,

At page 106 of “Descent of Man” I find a sentence: “as I have so lately endeavoured to shew that the social instincts—the prime principle of man’s moral constitution39.—” & a footnote:

‘The Thoughts of Marcus Aurelius, &c p. 139. But I cannot find in any list of books under your name one with that title & I never heard of it1  Can you tell me its full title & where to get it? I am amazed at my ignorance of it!

Yours ever, | Lawson Tait

I am engaged in a short “Kritic of the Individuum” which may interest you & of which I hope to send you a copy in a day or two.2 It is intended as a mite towards evolutionary theosophy.

In Descent 1: 106, CD paraphrased the following passage from Aurelius 1862: ‘The prime principle then in man’s constitution is the social.’ The title of the work by Marcus Aurelius is usually translated as Meditations.
The article by Tait has not been found; he had recently written on the evolution of morality (L. Tait 1876; see Correspondence vol. 24, letter from Lawson Tait, 4 August [1876] and n. 3).
