…nothing but psychology to go on, yet now you’ ve gone on to mathematics…
” “… I have myself admitted candidly several times already that that psychology can be taken in two ways and that the second way is stronger and looks far more probable, and that apart from that I have as yet nothing against you. An though I shall put you in prison and indeed have come – quite contrary to etiquette – to inform you of it beforehand, yet I tell you frankly, also contrary to etiquette, that it won’t be to my advantage. […] I’ve come to you with a direct and open proposition – that you should surrender and confess. It will be infinitely more to your advantage and to my advantage too, for my task will be done. Well, is this open on my part or not?”
Raskolnikov thought a minute.
“Listen, Porfiry Petrovich. You said just now you have nothing but psychology to go on, yet now you’ve gone on to mathematics.”
From the novel “Crime and Punishment” by Fyodor Dostoyevsky (1866)
An excerpt from chapter II of part VI of the novel. Raskolnikov, the book’s central character, reacts to Porfiry Petrovich’s psychological manipulation towards confession of his crime.
