Background: Raymond Bernard Cattell (20 March 1905 - 2 February 1998) was a British and American psychologist, known for his psychometric research into intrapersonal psychological structure. His work also explored the basic dimensions of personality and temperament, the range of cognitive abilities, the dynamic dimensions of motivation and emotion, the clinical dimensions of abnormal personality, patterns of group syntality and social behavior, applications of personality research to psychotherapy and learning theory, predictors of creativity and achievement, and many multivariate research methods including the refinement of factor analytic methods for exploring and measuring these domains. Cattell authored, co-authored, or edited almost 60 scholarly books, more than 500 research articles, and over 30 standardized psychometric tests, questionnaires, and rating scales. According to a widely cited ranking, Cattell was the 16th most eminent, 7th most cited in the scientific journal literature, and among the most productive, but controversial psychologists of the 20th century.
Context: Rather than pursue a "univariate" research approach to psychology, studying the effect that a single variable (such as "dominance") might have on another variable (such as "decision-making"), Cattell pioneered the use of multivariate experimental psychology (the analysis of several variables simultaneously). He believed that behavioral dimensions were too complex and interactive to fully understand variables in isolation. The classical univariate approach required bringing the individual into an artificial laboratory situation and measuring the effect of one particular variable on another - also known as the "bivariate" approach, while the multivariate approach allowed psychologists to study the whole person and their unique combination of traits within a natural environmental context. Multivariate experimental research designs and multivariate statistical analyses allowed for the study of "real-life" situations (e.g., depression, divorce, loss) that could not be manipulated in an artificial laboratory environment.  Cattell applied multivariate research methods across several intrapersonal psychological domains: the trait constructs (both normal and abnormal) of personality, motivational or dynamic traits, emotional and mood states, as well as the diverse array of cognitive abilities. In each of these domains, he considered there must be a finite number of basic, unitary dimensions that could be identified empirically. He drew a comparison between these fundamental, underlying (source) traits and the basic dimensions of the physical world that were discovered and presented, for example, in the periodic table of chemical elements.  In 1960, Cattell organized and convened an international symposium to increase communication and cooperation among researchers who were using multivariate statistics to study human behavior. This resulted in the foundation of the Society of Multivariate Experimental Psychology (SMEP) and its flagship journal, Multivariate Behavioral Research. He brought many researchers from Europe, Asia, Africa, Australia, and South America to work in his lab at the University of Illinois. Many of his books involving multivariate experimental research were written in collaboration with notable colleagues.

Problem: Background: Swami Vivekananda (Bengali: [Sami bibekanondo] ( listen); 12 January 1863 - 4 July 1902), born Narendranath Datta (Bengali: [norendronath doto]), was an Indian Hindu monk, a chief disciple of the 19th-century Indian mystic Ramakrishna.  He was a key figure in the introduction of the Indian philosophies of Vedanta and Yoga to the Western world and is credited with raising interfaith awareness, bringing Hinduism to the status of a major world religion during the late 19th century. He was a major force in the revival of Hinduism in India, and contributed to the concept of nationalism in colonial India. Vivekananda founded the Ramakrishna Math and the Ramakrishna Mission.
Context: The Parliament of the World's Religions opened on 11 September 1893 at the Art Institute of Chicago as part of the World's Columbian Exposition. On this day, Vivekananda gave a brief speech representing India and Hinduism. He was initially nervous, bowed to Saraswati (the Hindu goddess of learning) and began his speech with "Sisters and brothers of America!". At these words, Vivekananda received a two-minute standing ovation from the crowd of seven thousand. According to Sailendra Nath Dhar, when silence was restored he began his address, greeting the youngest of the nations on behalf of "the most ancient order of monks in the world, the Vedic order of sannyasins, a religion which has taught the world both tolerance, of and universal acceptance". Vivekananda quoted two illustrative passages from the "Shiva mahimna stotram": "As the different streams having their sources in different places all mingle their water in the sea, so, O Lord, the different paths which men take, through different tendencies, various though they appear, crooked or straight, all lead to Thee!" and "Whosoever comes to Me, through whatsoever form, I reach him; all men are struggling through paths that in the end lead to Me." According to Sailendra Nath Dhar, "[i]t was only a short speech, but it voiced the spirit of the Parliament."  Parliament President John Henry Barrows said, "India, the Mother of religions was represented by Swami Vivekananda, the Orange-monk who exercised the most wonderful influence over his auditors". Vivekananda attracted widespread attention in the press, which called him the "cyclonic monk from India". The New York Critique wrote, "He is an orator by divine right, and his strong, intelligent face in its picturesque setting of yellow and orange was hardly less interesting than those earnest words, and the rich, rhythmical utterance he gave them". The New York Herald noted, "Vivekananda is undoubtedly the greatest figure in the Parliament of Religions. After hearing him we feel how foolish it is to send missionaries to this learned nation". American newspapers reported Vivekananda as "the greatest figure in the parliament of religions" and "the most popular and influential man in the parliament". The Boston Evening Transcript reported that Vivekananda was "a great favourite at the parliament... if he merely crosses the platform, he is applauded". He spoke several more times "at receptions, the scientific section, and private homes" on topics related to Hinduism, Buddhism and harmony among religions until the parliament ended on 27 September 1893. Vivekananda's speeches at the Parliament had the common theme of universality, emphasising religious tolerance. He soon became known as a "handsome oriental" and made a huge impression as an orator.  Sponsorship of Swami Vivekananda for Parliament of the World's Religions  In 1892, Swami Vivekananda stayed with Bhaskara Sethupathy, who was a Raja of Ramnad, when he visited Madurai and he sponsored Vivekananda's visit to Parliament of the World's Religions held in Chicago.
