I can now rejoice even in the falsification of a cherished theory, because even this is a scientific success.
As quoted in the Introduction of Conjectures and Refutations: The Growth of Scientific Knowledge (1963) by Karl Popper
In order that a "self" may exist there must be some continuity of mental experiences and, particularly, continuity bridging gaps of unconsciousness. For example, the continuity of our "self" is resumed after sleep, anaesthesia, and the temporary amnesias of concussion and convulsions.John Carew Eccles
I believe that there is a fundamental mystery in my existence, transcending any biological account of the development of my body (including my brain) with its genetic inheritance and its evolutionary origin. ... I cannot believe that this wonderful gift of a conscious existence has no further future, no possibility of another existence under some other unimaginable conditions.John Carew Eccles
I maintain that the human mystery is incredibly demeaned by scientific reductionism, with its claim in promissory materialism to account eventually for all of the spiritual world in terms of patterns of neuronal activity. This belief must be classed as a superstition ... we have to recognize that we are spiritual beings with souls existing in a spiritual world as well as material beings with bodies and brains existing in a material world.John Carew Eccles
Our coming-to-be is as mysterious as our ceasing-to-be at death. Can we therefore not derive hope because our ignorance about our origin matches our ignorance about our destiny? Cannot life be lived as a challenging and wonderful adventure that has meaning yet to be discovered? (95)John Carew Eccles
