Where is 'science' in the heirarchy of human knowledge? It is above some things, and below others. Certainlty when it comes to finding out anything that can be found out about the natural world, it is the only method. That's what science is, and does. It is a method for finding things out, which also enables us to get many things done. In that realm it is indispensable.
But I am of the firm view that human beings and the nature of human existence - the kinds of issues that Buddhism addresses - are not in scope for the scientific method. They are much more immediate, intimate, and up-close. That is why they are suitable topics for philosophy, self-inquiry, and meditation. As soon as you start to say that these things can be made the object of scientific enquiry, then you are immediately beginning to treat people as objects. That is the major shortcoming of materialism, and it is highly insidious, and happening a great deal in our modern world. It needs to be pointed out, criticized and resisted. You don't have to be anti-science to say that, but if you do say it, you will often be characterised as 'anti-science'. That says a lot.
See H H The Dalai Lama's statement on Science at the Crossroads
. H H has always had a strong interest in science, meets regularly with scientists, and is Patron of the Mind and Life conferences. Yet he too recognizes the dangers of materialism:
The danger...is that human beings may be reduced to nothing more than biological machines, the products of pure chance in the random combination of genes, with no purpose other than the biological imperative of reproduction.
