The website Big Questions Online is self-described this way:
Big Questions Online aims to explore the “big questions” of human purpose, existence, and the universe — from science and religion to markets and morals. We feature essays by leading thinkers: philosophers, scientists (including Nobel laureates), theologians and clergy, journalists, and writers from other fields. Our essays often bridge the disciplines, and they are short and clearly written, so that readers from all walks of life can be enriched and enlightened by thinking about the big questions that are fundamental to who and what we are.
BQO tackles questions relating to Behavior, Cosmology, Markets, Evolution, Morality, Philosophy, Reason, Religion, and Science. Browse the BQO archives for a sampling of what it offers:
“Are Developmental Mistakes Essential for Evolution?”
“Is Character Necessary for Moral Behavior?”
“Can Private Vice Produce Public Virtue?” (The answer to that had better be “yes,” because market capitalism is based on that very assumption.)
“How Can We Cultivate a Practical Wisdom?” (This question is posed and answered by the estimable Barry Schwartz.)
“How Do We Develop and Maintain Humility?”
“Why Do We Sleep?’
The essays are all relatively short, but for readers who really want to think these things through, each essay is followed by discussion questions. It’s almost like being in school! Just for fun, you could hold a “Big Questions” group at your local library (it would be like “Socrates Café”); or you could just show up at your neighborhood bar armed with copies of BQO essays, then ask the bartender to kindly turn off the TVs and the jukebox so that people could discuss “What Is the Difference between Joy and Happiness?” You’ll be the talk of the town!
If you’re less philosophically inclined but interested in staying up to date on the latest scientific developments: Real Clear Science comes from the same folks who bring you Real Clear Politics, Real Clear Religions, Real Clear Books, and more. On any given day, Real Clear Science offers you such delights as “13 Signs You Work with a Psychopath,” “What Caused Voices in Joan of Arc’s Head?” and “Crows Use Tools to Move Objects.” If those don’t fascinate you, how about “Brain Chips, Synthetic Blood Creep Out Americans”? Or “Cockroach Milk: The Next Superfood?” The articles and essays are taken from a variety of sources and cover an eclectic range of topics, the common denominator being the conviction that only Science can lead us to Truth—although, in fairness, some of the selections actually betray a healthy skepticism towards that notion.
By the way: the voices in Joan of Arc's head were most likely caused by a form of epilepsy, or so we're told. The scientists who offer that surmise--which they could test if only they could get a sample of the Maid's DNA!--never consider the possibility that Joan's voices were actually divine communications; if you were intrigued by that option, you'd probably have to go to Real Clear Religion.
Finally: let’s say you wanted to refresh your memory regarding the political views of the anti-Federalists. You could, of course, turn to Wikpedia, where you would no doubt find a useful summary; but if you’d like the option to pursue the subject in depth and even to consult primary sources, I suggest you visit the Online Library of Liberty. OLL will provide you this succinct explanation:
The anti-federalists were a group who had reservations about ratifying the U.S. Constitution when it was first proposed. Some thought the Articles of Confederation were sufficient to unite the sovereign American states; others were concerned that the rights of the states and of individuals needed additional protection and so supported a Bill of Rights; others were concerned that the Federalists wanted to recreate a head of state with powers too much like those of the British monarch against whom they had just fought a war of independence.
More importantly, OLL won’t stop there; instead, it will link you directly to a variety of documents, biographies, and discussion forums. Yes, I know that Wikipedia also includes such links, but OLL is more specialized and provides, in my estimation, a better and deeper take on its subjects. The OLL even offers complete books, as well as articles on topics like “Adam Smith on Why People Obey and Defer to Their Rulers,” “The Art of the Levellers,” and “The Corrupting Influence of Power in Shakespeare’s Plays”.
Full disclosure: the Online Library of Liberty is a project of Liberty Fund, a well-known libertarian foundation. If you’re worried about ideological contamination—well, you’ve been warned.
