Et qui n’est chaque fois ni tout a fait la même,
ni tout a fait une autre.

‘And each time she is neither entirely the same,
nor entirely different.’

‘Mon rêve familier’
Paul Verlaine, 1866

In delusions, everything which one wishes and fears may find its level of expression and as far as can be judged by the present state of our knowledge, many other things, perhaps even everything which can be experienced or thought.

Eugen Bleuler, 1911
