The basic philosophical assumption that underlies all the systems theories is that, it views human beings holistically. Human beings have a physical and emotional body as well as a linkage to society. Structural functionalism assumes that stability is necessary for human flourishing. On the other hand, dynamic systems theory states that radical changes, and adaptability are the factors that contribute to a smooth functioning of human life and society. Deep ecology, and ecofeminisim assume that human beings should have self-awareness, non-violence, compassion, and connectedness to all things. Lastly, ecosystems theory assumes that humans strive for a "goodness of fit" in their environment. Two of these theories (structural functionalism and ecosystem theory) in particular, conflict with social work values of diversity, social justice, and self-determination. Ecosystems theory views sexism and racisim as transactional processes that promote a "goodness of fit" to the environment. While, functionalism strives to maintain whatever values society holds, such as racism, sexism, and homophobia. As you can see, implementing such theories into social work practice can be extremely detrimental.
