Somewhere on the borderline between the invented and the real lies the question of the human spirit and its associated qualities, such as love and aesthetic appreciation. I grant that these qualities, or at least their physiological appurtenances, exist. The question, then, is whether science can elucidate them.
If science can, it has a lot of catching up to do. We've been
elucidating that aspect of the human condition for a
very long time. Certainly not as long as our efforts to understand and
control the world around us, but apparently the need to wrap some sort of aesthetic or spiritual narrative around the mechanics of existence occurred as an important part of the development of the species. Certainly the requirements of aesthetic priorities
continue today as an integral part of our physical existence on the planet.
Form follows function, and part of the function of any tool we have ever used is its potential to propel us into an uncertain future.
There is no evidence that it cannot, and it is not unreasonable to suppose that it can without resorting to supernatural importations. Love is a complex emotion, involving genetically controlled responses, hormonal excretions, and intellectual reflections and considerations. Science can elucidate such a condition, even though it will probably never purport to be able to predict whether one individual will fall in love with another...
Atkins offers us an optimistic expectation that science will be able to measure and quantify the human spirit, but is still unable to offer any hope that quantification will produce predictability. And he does it by denying the need for any evidence that it can accomplish that goal. Such an optimistic expectation of success using an appeal to ignorance sounds a lot like an expression of faith. Especially after a five paragraph paean to the virtues of science over religion. I guess science truly works in mysterious ways.
