It looks like the author [1] is associated with The Book of Life [2] which is referenced on the site you linked [3]. Likely all owned by the same person.
Edit: I agree with TACIXAT that both of these were written by Alain de Botton; the confusion came about because the older versions were unsigned, so it's easy to worry that the newer version could have been plagiarized. There's also a norm of revealing the publication history of your own stuff when you rework or republish it, so maybe the Times should have said "A version of this essay appeared in The Philosopher's Mail and appears in The Book of Life" to avoid any ambiguity.
