Ecologically responsible policies are concerned only in part with pollution and resource depletion. There are deeper concerns which touch upon principles of diversity, complexity, autonomy, decentralization, symbiosis, egalitarianism, and classlessness.

Biophilia is Edward O. Wilson's most personal book, an evocation of his own response to nature and an eloquent statement of the conservation ethic. Wilson argues that our natural affinity for life―biophilia―is the very essence of our humanity and binds us to all other living species.

“William James is a towering figure in the history of American thought--without doubt the foremost psychologist this country has produced. His depiction of mental life is faithful, vital, and subtle. In verve, he has no equal.... “There is a sharp contrast between the expanding horizon of James and the constricting horizon of much contemporary psychology. The one opens doors to discovery, the other closes them. Much psychology today is written in terms of reaction, little in terms of becoming. James would (...) say that a balance is needed, but that only by assuming that man has the capacity for growth are we likely to discover the scope of this same capacity.” —from the introduction by Gordon W. Allport. (shrink)

The broaden‐and‐build theory (CitationFredrickson, 1998, Citation2001) hypothesises that positive emotions broaden the scope of attention and thought‐action repertoires. Two experiments with 104 college students tested these hypotheses. In each, participants viewed a film that elicited (a) amusement, (b) contentment, (c) neutrality, (d) anger, or (e) anxiety. Scope of attention was assessed using a global‐local visual processing task (Experiment 1) and thought‐action repertoires were assessed using a Twenty Statements Test (Experiment 2). Compared to a neutral state, positive emotions broadened the scope (...) of attention in Experiment 1 and thought‐action repertoires in Experiment 2. In Experiment 2, negative emotions, relative to a neutral state, narrowed thought‐action repertoires. Implications for promoting emotional well‐being and physical health are discussed. (shrink)
