Six-factor model of psychological well-beingThe six-factor model of psychological well-being is a theory developed by Carol Ryff which determines six factors which contribute to an individual's psychological well-being, contentment, and happiness. Psychological well-being consists of self-acceptance, positive relationships with others, autonomy, environmental mastery, a feeling of purpose and meaning in life, and personal growth and development. Psychological well-being is attained by achieving a state of balance affected by both challenging and rewarding life events.
AdiaphoraAdiaphoron (ædɪˈæfərɒn,_ædiˈæfərɒn; plural: adiaphora; from the Greek ἀδιάφορον (pl. ἀδιάφορα), meaning "not different or differentiable") is the negation of διαφορά diaphora, "difference". In Cynicism, adiaphora represents indifference to the s of life through ascetic practices which help one become free from influences – such as wealth, fame, and power – that have no value in nature. Examples include Diogenes' practice of living in a tub and walking barefoot in winter.
SpeusippusSpeusippus (spjuːˈsɪpəs; Σπεύσιππος; c. 408 – 339/8 BC) was an ancient Greek philosopher. Speusippus was Plato's nephew by his sister Potone. After Plato's death, c. 348 BC, Speusippus inherited the Academy, near age 60, and remained its head for the next eight years. However, following a stroke, he passed the chair to Xenocrates. Although the successor to Plato in the Academy, Speusippus frequently diverged from Plato's teachings.
