“T think, therefore I am”: René Descartes’s famous statement speaks to his
having no doubt about his own existence. His original phrase was in French,
Je pense, donc je suis, published in 1637 in his Discourse on the Method. The
more widely quoted Latin version, cogito ergo sum, appeared in 1644 in his
Principles of Philosophy.
“J feel, therefore I am”: prominent exponents for the centrality of emotion
in human experience include Jaak Panksepp and Antonio Damasio; see
Panksepp (1998), Panksepp and Biven (2012), and Damasio (1999).
For a nuanced treatment of definitions related to emotion and mood, as well
as excellent discussions of many important concepts in the science of emo-
tion, see Ekman and Davidson (1994).
