Here are two excerpts from:
An Evolutionary Perspective on the Relationship between Humans and their Surroundings: Geoengineering, the purpose of life & the nature of the universe
"The purpose of this chapter is two-fold. Firstly, following our consideration in Chapter One of humans doubting their naturalness, I seek to consider in greater depth why this is so. I claim that the answer lies in the realm of advanced tool use because this generates a ‘sense of specialness’. This consideration is to be found in Section 7.1 – A sense of specialness. Secondly, I seek to consider all of the attributes which, it seems to me, could plausibly be believed to create a chasm between a human and all of their non-human surroundings. One can fruitfully think of this consideration as occurring within the ‘static view’ – take a human, take a non-human part of the universe, compare them: Does the human have a chasm-creating attribute? This is the subject of Section 7.2 – Do humans have a unique attribute?"
"So far we have considered a number of attributes which are widely believed to create a chasm between humans and the vast majority (or all) of their surroundings. For example, human surroundings are ‘natural’ whilst humans are not natural, human surroundings are nonminded whilst humans have minds, and human surroundings are wholly devoid of ‘what-it-is-likeness’ whilst humans have ‘what-it-is-likeness’. Furthermore, I have also sought to understand why this situation obtains. Imagine that one was told that there was a universe which was created in a Big Bang and that it had been very gradually evolving slightly different arrangements and patterns ever since, and that nothing new had been added to this universe, that that which exists now is that which had always existed. On hearing this story the most plausible thing to believe would be that there were no chasms in this universe – all parts of the universe would be qualitatively similar throughout. However, this is clearly not what one typically believes when one is a human situated within such a universe. I have explored why this might be so by exploring the way in which the human perceptual apparatus has evolved to perceive its surroundings in a particular way, and concluded that this constrained way in which perceptions arise is a central factor underpinning the creation of world views which have chasms at their core."
