Peter Singer’s almost reverential review… of On What Matters by Derek Parfit claims that the work is the “most significant work in ethics since Sidgwick’s masterpiece [The Methods of Ethics] was published in 1873”. On the contrary, two much more important books were published by Friedrich Nietzsche – Beyond Good and Evil (1886) and On the Genealogy of Morality (1887).

The argument is nonsense, of course. For you cannot disprove a person’s preference by replacing it with one of your own. This is the academic equivalent of saying vanilla ice cream is better than choc-chip because I prefer it.
