Problem: Wilhelm Stekel (German: ['Ste:k@l]; 18 March 1868 - 25 June 1940) was an Austrian physician and psychologist, who became one of Sigmund Freud's earliest followers, and was once described as "Freud's most distinguished pupil". According to Ernest Jones, "Stekel may be accorded the honour, together with Freud, of having founded the first psycho-analytic society"; while he also described him as "a naturally gifted psychologist with an unusual flair for detecting repressed material." He later had a falling-out with Freud, who announced in November 1912 that "Stekel is going his own way". His works are translated and published in many languages.

Stekel made significant contributions to symbolism in dreams, "as successive editions of The Interpretation of Dreams attest, with their explicit acknowledgement of Freud's debt to Stekel": "the works of Wilhelm Stekel and others...since taught me to form a truer estimate of the extent and importance of symbolism in dreams". Considering obsessional doubts, Stekel said, In anxiety the libido is transformed into organic and somatic symptoms; in doubt, the libido is transformed into intellectual symptoms. The more intellectual someone is, the greater will be the doubt component of the transformed forces. Doubt becomes pleasure sublimated as intellectual achievement. Stekel wrote one of a set of three early "Psychoanalytic studies of psychical impotence" referred to approvingly by Freud: "Freud had written a preface to Stekel's book". Related to this may be Stekel's "elaboration of the idea that everyone, and in particular neurotics, has a peculiar form of sexual gratification which is alone adequate". Freud credited Stekel as a potential forerunner when pondering the possibility that (for obsessional neurotics) "in the order of development hate is the precursor of love. This is perhaps the meaning of an assertion by Stekel (1911 [Die Sprache des Traumes], 536), which at the time I found incomprehensible, to the effect that hate and not love is the primary emotional relation between men". The same work is credited by Otto Fenichel as establishing 'the symbolic significance of right and left...right meaning correct and left meaning wrong '. Less flatteringly, Fenichel also associated it with "a comparatively large school of pseudo analysis which held that the patient should be 'bombarded' with 'deep interpretations,'" a backhanded tribute to the extent of Stekel's early following in the wake of his break with Freud.

How did he make these contributions?

Problem: Arabs (; Arabic: 'arab ISO 233 'arab, Arabic pronunciation ['?arab] ( listen)) are a population inhabiting the Arab world. They primarily live in the Arab states in Western Asia, North Africa, the Horn of Africa and western Indian Ocean islands.

The earliest documented use of the word "Arab" to refer to a people appears in the Kurkh Monoliths, an Akkadian language record of the ninth century BCE Assyrian conquest of Aram, which referred to Bedouins of the Arabian Peninsula under King Gindibu, who fought as part of a coalition opposed to Assyria. Listed among the booty captured by the army of king Shalmaneser III of Assyria in the Battle of Qarqar are 1000 camels of "Gi-in-di-bu'u the ar-ba-a-a" or "[the man] Gindibu belonging to the Arab (ar-ba-a-a being an adjectival nisba of the noun 'arab). The related word 'a'rab is still used to refer to Bedouins today, in contrast to 'arab which refers to Arabs in general. The oldest surviving indication of an Arab national identity is an inscription made in an archaic form of Arabic in 328 using the Nabataean alphabet, which refers to Imru' al-Qays ibn 'Amr as "King of all the Arabs". Herodotus refers to the Arabs in the Sinai, southern Palestine, and the frankincense region (Southern Arabia). Other ancient Greek historians like Agatharchides, Diodorus Siculus and Strabo mention Arabs living in Mesopotamia (along the Euphrates), in Egypt (the Sinai and the Red Sea), southern Jordan (the Nabataeans), the Syrian steppe and in eastern Arabia (the people of Gerrha). Inscriptions dating to the 6th century BCE in Yemen include the term "Arab". The most popular Arab account holds that the word "Arab" came from an eponymous father called Ya'rub who was supposedly the first to speak Arabic. Abu Muhammad al-Hasan al-Hamdani had another view; he states that Arabs were called Gharab ("West") by Mesopotamians because Bedouins originally resided to the west of Mesopotamia; the term was then corrupted into "Arab". Yet another view is held by al-Masudi that the word "Arabs" was initially applied to the Ishmaelites of the "Arabah" valley. In Biblical etymology, "Arab" (in Hebrew Arvi ) comes both from the desert origin of the Bedouins it originally described (Arava means wilderness). The root '-r-b has several additional meanings in Semitic languages--including "west/sunset," "desert," "mingle," "mixed," "merchant," and "raven"--and are "comprehensible" with all of these having varying degrees of relevance to the emergence of the name. It is also possible that some forms were metathetical from '-B-R "moving around" (Arabic '-B-R "traverse"), and hence, it is alleged, "nomadic."
