בד, לבד v. נגד, כנגד

Note the seeming superflousness in the preceding 'ל' and 'כ' of לבד and כנגד, respectively.

זהר הקדוש, ויקרא דף מ"ד ע"ב -- וכי לבדו הוה, והא כתיב, (בראשית ה) זכר ונקבה בראם. ותנינן אדם דו פרצופין אתברי, ואת אמרת, לא טוב היות האדם לבדו. אלא דלא אשתדל בנוקביה, ולא הות ליה סמך לקבליה, בגין דהות בסטרוי, והוו כחדא מאחורא, וכדין הוה האדם לבדו.

בד meaning "solitary/unitary" by itself (see Yoma 71b), לבד then does not really mean "alone" but rather "towards solitarianism/solidarity" even if being done by more than one person (see Janus' Groupthink in Sociology as an example).

The difference between נגד and כנגד being clearly obvious then:
 כנגד -  "like" or "as if to be" נגד, but in truth not נגד at all because it's ultimately towards a mutual consensus and השלמה in the larger scheme. Hence the meaning of כנגד as complementary/alongside/ parallel to.

לא טוב היות האדם לבדו אעשה לו עזר כנגדו


[Also, besides for "bad"/ בד having negative connotations in both english and persian, see שער הכוונות תפלת השחר ג that kabbalistically as well בד is related to negative realms]

City Life and Evil

There is an abundance of sociological literature on the challenges and detriments of city life: the migration from primary to secondary relationship groups, from gemeinschaft to gesellschaft, from a mindset of mutual kinship to the expedient rat-race of "every man for himself" (essentially). Notably in the writings of Georg Simmel, Ferdinand Tonnies, and Louis Wirth among others (though I've read none of their works directly myself, only through my sociology textbooks).

A small excerpt of Wikipedia on Wirth which I think expresses it well:

Wirth writes that urbanism is a form of social organisation that is harmful to culture, Wirth details the city as a “Substitution of secondary for primary contacts, the weakening of bonds of kinship, the declining social significance of the family, the disappearance of neighbourhood and the undermining of traditional basis of social solidarity”.^[1]   Wirth was concerned with the effects of the city upon family unity, and he believed urbanization leads to a ‘low and declining urban reproduction rates … families are smaller and more frequently without children than in the country’. Wirth continues, marriage tends to be postponed, and the proportion of single people is growing leading to isolation and less interaction.

What I'd like to point out is that the hebrew word for 'city' עיר touches on both the positive and negative aspects of urbanization.

Similar to the Gemara's (Sotah 17a) comparing of איש and אש
איש ואשה, זכו, שכינה ביניהם, לא זכו, אש אוכלתן
so too I'd suggest where you have a "זכו" you have an עיר, where you have a "לא זכו" you have a ער/רע.

(note the Zohar teaches the letter 'yud' being representative of brit, committed relationship)

Intro to Sociology - מושל מקשיב על דבר שקר כל משרתיו רשעים

Started a course in Sociology. My textbook (John Macionis) begins with explaining Sociology as (my loose translating from Hebrew to English)

Sociological insight is essentially the recognition that the social world guides our actions and choices similar to the change in seasons affecting our manner of dress.... and since the sociologists have abundant knowledge as to the modes of action of the society, they can analyze and foresee with a certain degree of precision how we (individuals) will act in the future.

There's of course a lot more to quote but I like to keep my writing brief. In any event, my thought being that the verse in Mishlei 29 is really appropriate to Sociology.

  מושל מקשיב על דבר שקר כל משרתיו רשעים  because the individuals within any system, by definition, must function within the underlying foundations of that system, be they good or bad. On the micro level, of course, each individual has free choice for good or bad, but there's no escaping his place in the larger scope of the system that he's in... and if that larger scope is a system of מושל מקשיב על דבר שקר then he is, on that level of scale, a משרת רשע.   (See Chullin 4b)

In general, it seems to me that Sociology deals heavily with the issues of ספירת מלכות as explained by R' Matis in his Sefirat HaOmer shiurim among others...

[I would further throw out the possibility (most probably out of aarogance and carpriciousness) that the 3 Paradigms of Sociology: (1) Structural Functionalism, (2) Conflict Theory, and (3) Symbolic Interactionism are essentially loose emphasis' of different dimensions in מלכות--  aיסוד שבמלכות, bגבורה שבמלכות, and cמלכות שבמלכות, respectively. Needs further thought...]
