It's odd, but from the front row of the mezzanine, I believe I caught and understood pretty much everything that came out of Beale's mouth. The character does get quite excited at times and tends to speak quickly when he happens upon good ideas for his speech, but all he's really talking about and trying to work out are the arguments supporting a philosophical view that there are indeed moral absolutes in the universe; that there is such a thing as objective good and evil; that there is a God (or perhaps two gods as the play posits), although he/she/it/they may be unknowable.
He contrasts this viewpoint (a minority point of view in academia) with that of most philosophers who believe in a sort of moral relativism, that good vs evil and right vs. wrong are entirely a subjective matter, depending on a person's own beliefs, tastes, background, culture etc....Archie is a prime exponent of this view and could, if pressed, philosophically justify and explain his affair with George's wife, the murder of the lead jumper, the archbishop etc (it struck me that he was not unlike some of our political leaders). Notice that the murders are never solved and the perpetrators are never brought to justice -- this is because in Stoppard's absurdist critique of modern politics and morality, such things don't matter because there is no true justice anymore because "right and wrong" have become "touchy feely" notions rather than concrete ethical underpinings of society.
George (who represents Stoppard) is critical of this view because he wonders how can one live in a world that rejects any basic or fundamental morality, a world without any ultimate meaning where even the word of God isn't taken as the final word on anything. The moral relativists (represented by Archie and "rad lib" jumpers gymnastics team -- their lack of a basic belief system allows them to jump about philosophically and argue any ethical quandry from any position) don't believe in anything that can't be proven empirically, scientifically and/or mathematically (and given that we all know how easy it is to manipulate statistics to support any side of any argument, they, in effect, don't really believe in anything). They represent a modernist scientific view where man is the center of the universe and where faith is shunned and the only things that can be believed in are things that can be seen and proven. This brave new world which exalts the head over the heart has lead to George's wife Dotty going insane -- when men land on the moon and it is revealed to be just another barren wasteland, rather than a shining, romantic symbol of hope, longing, love..... she finds herself unable to sing her old act anymore which contained many songs that presented an idealized notion of the moon. Without the moon (in effect, without anything to hope for and dream for) her life has lost all meaning.
I could certainly go on, but suffice it to say that it's a fascinating play, expertly performed and dazzlingly staged -- one of the true highlights of the season. Beale is extraordinary (and no he didn't seem overly fey to me) managing to make some very difficult dialogue seem fresh and spontaneous and quite intelligible to my ears. Leveaux has outdone himself, making a challenging straight play "sing and dance" at least as much as any of his musicals, yet conveying its ideas as clearly and coherently as one could possibly hope for.
I don't agree that "Invention of Love" was a better play -- this one's FAR more ambitious. In this play, written shortly after man first landed on the moon, Stoppard employs vaudeville and music hall traditions, Orton farce, Monty Python absurdity, Wildean word play and intellectual musings all his own to take on the meaning of life, of god and faith in our contemporary world and considers whether as we continue to advance technologically and scientifically, whether we as people (along the institutions we create -- the government, the church, medical science et al) are becoming less and less human and losing touch with our souls and our moral compasses. An indisputably great work, getting perhaps a definitive production currently at The Brooks Atkinson.
