I have more than once tried to analyse this apparently deliberate form of self-torture that seems common to so many people in face of the extinction of a valued life, human or animal, and it springs, I think, from a negation of death, as if by summoning and arranging these subjective images one were in some way cheating the objective fact. It is, I believe, an entirely instinctive process, and the distress it brings with it is an incidental, a by-product, rather than a masochistic end.

We have long laboured under an obtuse presupposition that the senses by which other living creatures perceive their world must to a great extent resemble our own; but in fact we are, by scientific invention, only now beginning to approach methods of perception that the whales have always owned as their birthright.

There is something deeply awe-inspiring about the sight of any living creatures in incomputable numbers; it stirs, perhaps, some atavistic chord whose note belongs more properly to the distant days when we were a true part of the animal ecology; when the sight of another species in unthinkable hosts brought fears or hopes no longer applicable.

Symbols, for me and for many, of freedom, whether it be from the prison of over-dense communities and the close confines of human relationships, from the less complex incarceration of office walls and hours, or simply freedom from the prison of adult life and an escape into the forgotten world of childhood, of the individual or the race. For I am convinced that man has suffered in his separation from the soil and from the other living creatures of the world; the evolution of his intellect has outrun his needs as an animal, and as yet he must still, for security, look long at some portion of the earth as it was before he tampered with it.

In moments of peace such as I experienced that day with Edal there exists some unritual reunion with the rest of creation without which the lives of many are trivial. 'Extinct' applies as much to an essential mental attitude as to the vanished creatures of the earth such as the Dodo. We can no longer await some scientific revelation to avoid the destruction of our species in this context; the evidence is all there, the writing on the wall. The way back cannot be the same for all of us, but for those like myself it means a descent of the rungs until we stand again amid the other creatures of the earth and share to some small extent their vision of it, even though this may be labelled Wordsworthian romanticism.
