Innovators are individuals who embrace the culturally approved goals of success (such as wealth) but lack the legitimate means to attain them, leading them to adopt unconventional or illegal methods to achieve those goals.

Functionalism, particularly in the tradition of Émile Durkheim, posits that society functions like an organism. For this organism to remain stable, members must share a common set of values and beliefs, known as moral consensus. This shared understanding provides the social glue necessary to prevent anomie and ensure that individuals work together for the collective good of the social system.

The evolutionary perspective, heavily influenced by early thinkers like Herbert Spencer, posits that societies undergo a natural progression. This view suggests that social structures evolve over time, moving from simple, undifferentiated forms toward increasingly complex, specialized, and integrated systems, mirroring biological evolutionary processes applied to human social organization.

The functionalist perspective views society as a complex system where each part works together to maintain the whole. It emphasizes the role of social institutions in promoting social order and stability, often comparing society to a biological organism where each organ performs a specific function necessary for survival.

Functionalism is a major theoretical framework in sociology that views society as a complex system whose parts work together to promote solidarity and stability. Talcott Parsons is often considered the most influential functionalist theorist, while Robert Merton contributed significantly by distinguishing between manifest and latent functions. Kingsley Davis also applied functionalist analysis to social stratification, making all three key contributors to this perspective.

Functionalism views society as a complex system whose parts work together to promote solidarity and stability. It assumes that social institutions, such as family, education, and religion, function to meet the needs of society. This perspective emphasizes social consensus, where members of society generally agree on common values and norms, ensuring the system remains orderly and functional.

Talcott Parsons, a prominent functionalist, argued that the nuclear family serves two irreducible functions: primary socialization, where children internalize societal norms and values, and personality stabilization, which provides emotional support for adult members to cope with the stresses of society. These functions are viewed as vital for maintaining the stability and equilibrium of the broader social system.

Functionalist theory, particularly the Davis-Moore thesis, posits that social stratification is necessary because some roles are more functionally important than others and require greater talent or training. Because these roles are often demanding, difficult, or less pleasant, society must provide differential rewards to motivate the most qualified individuals to fill them. This ensures that the essential functions of society are performed effectively by the most capable members.

Ralf Dahrendorf is a prominent figure associated with conflict theory, specifically known for his critique of functionalism and his focus on power dynamics and social inequality. In contrast, Emile Durkheim, Talcott Parsons, and Robert Merton are foundational figures in the development of functionalist theory, which emphasizes social stability, consensus, and the interconnectedness of social institutions.

Robert K. Merton distinguished between manifest functions, which are the intended and recognized consequences of social activities, and latent functions, which are the unintended or hidden consequences. Recognizing latent functions is crucial for a complete sociological analysis, as it reveals how social institutions perform roles that are not immediately apparent to the participants involved.
