Natural sciences deal with actions and interactions concerning matter, energy - between, within themselves - in space and time. Social sciences deal with human origin socially, origin and evolution of social, ideological, religious and other institutions conceived, designed, developed and implemented by human beings.
Philosophy deals with abstractions of origin, creation, development and evolution of human ideas, theories, insight, understanding, thoughts and feelings; their structures and forms.
Spirituality deals with the specificity of understanding human mental functions, structure and function and management of mind and its activities.
The human beings use all this knowledge and expertise to develop civilization, culture, fine-arts, skills and instruments and gadgets to comfort their life, regulate their behaviour and manage themselves socially. They also wrongly use this knowledge to cause pain and hurt to fellow humans and disturb peaceful living of theirs. This much endeavour of humans makes them unique in life-systems, living and non-living matter and whole creation/evolution.
