Science is not nature. Science is not truth. Science is the process by which humans try to uncover truths about nature.
Nature is objective and exists outside of humanity. We are products of nature and exist within it.
But science is socially constructed, because science can’t exist without us. Science is something that must be done. And because it only exists within the context of us messy political humans it reflects our messy political society. It’s biased and political and can be (and often is) wrong.
Science can be harmful. It can, and is, used to support and justify bigotry and hatred. And support harmful power structures. And justify whatever status quo those in power wish to maintain.
It also does amazing things and brings to light beauty and elegance and things previously unimaginable. It can also be used to fight against the damaging and harmful.
But these are two sides of the same coin. And if we really want science to be the best it can be we need to recognize that.
