|September 1, 2025
Summary
Eugenio Rignano's energetical vitalism proposed a unique "vital energy" for biological purposiveness. While lacking empirical proof, his ideas, particularly the centroepigenetic hypothesis, show surprising relevance to modern genetics.
Area of Science:
- Philosophy of Science
- History of Biology
- Biophilosophy
Background:
- Explores Eugenio Rignano's early 20th-century doctrine of energetical vitalism.
- Focuses on Rignano's attempt to explain biological purposiveness (teleology).
- Synthesizes concepts from energetics, neo-Lamarckianism, and mnemic theories.
Purpose of the Study:
- To analyze Rignano's energetical vitalism and its two core hypotheses: vital energy and centroepigenesis.
- To critique the doctrine's empirical support and historical significance.
- To assess the prescience of Rignano's ideas in light of contemporary scientific understanding.
Main Methods:
- Philosophical analysis of Rignano's doctrine.
- Historical contextualization within early 20th-century scientific trends.
- Critical evaluation informed by Hasok Chang's perspectives on scientific theories.
Main Results:
- Rignano's vital energy hypothesis lacks empirical validation.
- Vitalism holds historical significance beyond current physicalist perspectives.
- The centroepigenetic hypothesis demonstrates potential prescience regarding molecular genetics.
Conclusions:
- Vitalistic hypotheses remain logically defensible despite physicalist constraints.
- Rignano's work, though historical, offers insights into biological complexity and inheritance.
- Re-evaluating "outdated" theories like vitalism can reveal unexpected connections to modern science.

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

William James, John Dewey, and Charles Sanders Peirce were instrumental in founding functional psychology, which draws heavily from Darwin's theory of evolution by natural selection. This theory suggests that individual traits, including behaviors, are adapted to their environments through natural selection. At the heart of functionalism is the concept of adaptation, meaning that a trait enhances an individual's chances of survival and reproduction.

Humanistic psychology emerged in the mid-20th century as a response to the deterministic and pessimistic nature of behaviorism and psychoanalysis. While behaviorism focused on observable behaviors influenced by the environment and psychoanalysis delved into unconscious motivations, both theories suggested that human actions lacked free will. In contrast, humanistic psychology offers a perspective that emphasizes the innate potential for goodness and growth within every individual.

Power motivation and achievement motivation are two essential social motives identified by psychologist David McClelland. These motives influence behavior in various personal and professional contexts, shaping how individuals interact with others and pursue their goals.
Power motivation is characterized by the desire to influence, control, or have an impact on others. It is shaped by an individual's experiences, social environment, and cultural context. People with high power motivation are...

Self-Determination Theory (SDT), formulated by Richard Ryan and Edward Deci, explains that human motivation is driven by three fundamental psychological needs: autonomy, competence, and relatedness. When these needs are met, individuals experience personal growth, intrinsic motivation, and overall well-being.
Autonomy is the need to feel in control of one's actions and decisions. For example, a student who chooses their research topic is likely to be more engaged and motivated than one who...

Carl Rogers, a key figure in humanistic psychology, believed that individuals possess an innate potential for growth and fulfillment. According to his model of personality, three significant components define an individual: the organism, the self, and conditions of worth.
The organism refers to an individual's inherent blueprint, which Rogers saw as innately positive and directed toward helping others, unlike Freud's view of the id as driven by base impulses. The self is a person's...
