Our cause aligns with that of humanism.
Firstly, we agree with the general doctrine of humanism as embodied in the Humanist Manifesto III.
Secondly, our cause promotes the idea that a humanistic view has exceptional value in improving health and cooperation among humanity.
Thirdly, we argue that theism, even in its most benign-seeming forms, contradicts our core beliefs about the capability and responsibility of human beings, and detracts from our ability to achieve our stated mission.
Without the perspective of evolution, there is no basis for explaining the driving forces that shaped the development of the human body and brain. A great example is the limbic system in the brain: neurotransmitters provide chemical reward and threat signals in response to stimuli that historically helped or hindered our ability to survive in challenging circumstances. Knowing this origin of motivations resolves the conflict we encounter when human actions do not correspond to what we would often label as morally "good" or "bad". Failing to recognize this keeps us from fully understanding the foundations of human motivations and interactions (not to mention the mismatches and mistakes we have made in healthcare for lack of this perspective).
