Many in today's world are blinded by hatred by Josep Harrington, Shepherdstown and Violence Vanquished by Steven Pinker The Wall Street Journal
It appears that you are asking about two required articles.
I found the "Many in today’s world are blinded by hatred" article by actually going out to Google and searching for that title in quotes (as typed here). I was unable to find it in the Online Library.
The "Violence Vanquished" article appears in the Wall Street Journal. After logging into the Online Library, click the Find Now button underneath Find Articles. Click on the A-Z of Online Journal Titles link at the top of the list of databases and search for Wall Street Journal. Click on the first database name that appears on the list beneath the Wall Street Journal'sfirst entry: ProQuest ABI/INFORM Global New Platform and on the page that comes up, on the lower half of the page there is a search box where you can type in the title in quotes ("violence vanquished") and click search - which tells the database to search for those two words together in ONLY this journal. Your article is the only one that comes up, and is available as regular "full text."
