How much knows Lisa, don't you asked oneself such a question while watching another episode of hers? Everytime I see her another "flash" of intellect I wonder: is her knowlege really too deep in any aspect she metions? Yes, I understand that there's a plenty of moments that she cannot know by any circumstances; such as special areas of complex jobs, like an expert, programmer and such... Still I'm intersting what a baggage of information she gather at her present age.

There's only two moments I want to say about. Yet, she's like a "walking encyclopaedia" and we know that though such heavy books consists of huge amount of articles, it's profundity is very limited. Maybe and Lisa has such very general view of the majority of things in this world to talk about it? Especially with the people of Springfield who's not so well-educated in general? And Decland Desmond from "Scuse Me While I Miss The Sky" saw it clearly and says it to her during their first meting.

And one more point. There was a times when some information she talks about doesn't depend of her own description. Such a moment when she presents to Alex Whitney from "Lard of the Dance" episode their local school sights (the tree ) She realises that there's not too much to show to newbie, but can't do much and feels herself inconvenient. How do you think this quality of her character is useful to her - to feel a kind of guilty after the things in this world, that never depends of her efforts? I think it's rather bad habit, imparted by her parents, Marge especially.

Yay indeed.

I mostly agree with Serge here, Lisa is not so much book-smarts as she is "aware" of things. I think this awareness (social, moral, etc.) contributes to her factual knowledge. In other words, she knows how important it is to know things, and so realizes the benefits of things such as reading, art, school, and so forth. I believe all of her intelligence simply comes from a highly advanced maturity level.

Sometimes people who know a lot about everything can make the people they're with feel small, even if they don't mean to. I'm reminded of a line from L.A. Story (one of my favorite movies, by the way) where Steve Martin is taking his (girl)friend around to see the sights in L.A., and he tells her "You know, normally I don't like being around interesting people, because that means I have to be interesting too."

I think that it's good to be interesting at times, but to know when to draw the line between interesting and arrogant. If you know too much about everything, you end up appearing snobbish. I think this may also contribute to the anti-social attitude of Lisa. Whether or not she is a snob about her intellect, her peers may have labeled her this way. And so she is somewhat of an outcast at her school.

Blah, I'm rambling.

Well, wise from the birth seems to sound a bit loud. For it is so unbelievable that toddler Lisa has some knowledge how to do in life even not gathering the information about the world. But it fits her character, though looks like a little fancy. I never thought too much about her early moments of life, so it seems to be so fantastic to me.
As for computers - she's at the level of good user, not so much adult people do this. Remember how she intalled computer for her father (and again, after taking it from the thrash can ) Of course maybe she don't know all about the boot-sectors, msdos.sys and such special areas for it's just obsolescent today.

To realise the necessity of knowing well is not the only reason. She seems to take pleasure from study. And if you consider her intelligence only like a consequense of moral maturity, then how it could be joined with the fact that she's always has a free time while her homework ready? I mean to get all the knowledge that she has she must learn all the day long, staying in her room and reading the smart books

And one more. While saying on her getting snobbish, you said it adds to her anti-social side. And it's quite interesting to hear. Is it really so bad not to be a centre of everyone's attention? Everyone has it's own abilities to communicate and there's people who's more sociable, and the ones who's less. What really significant motive's need the person to communicate with others, except the getting information from them?

You said she can study well, and I just wonder. What if she doesn't as smart as she seems to be? It's not an easy thing to imagine, especially for a person like she. She must put a huge efforts to learn all this facts. When compared with Alison Taylor she was not so brilliant. And do not forget that almost any pupil can put oneself as "smart" in the second grade. Just the syllabus is quite easy to learn, not like in the high-grades, or the university.
No, I don't changed my opinion and still I think she's the smartest one in the Springfield. Just an assumption..

When I saw the last grabpic's upper part (slow downloading you know) I wondered where I did saw those there watches It was in only pair of hours today that I watched the "Lisa's Sax". And she was so nice when 3 years and 4 months.

Still I think that in our present time it's kinda ... pointless. If you are good hmm graphic designer for example, you'll do the work much better than any amateur. While such an amateur will reach the present skills of a designer by heart, the last one will reach another high level, unachievable now. So it kinda of rush when one member has an unquestionable advantage before the another one.
But I never will say that the struggle is pointless in any way. Lisa with her hunger for knowledge and childish legerity is in the very beginning of her own life to built. And we will never know exaclty what the way she  will choise. And to say honestly I'm even glad to know it, a year ago I longed to know her future, now it means nothing for me It's her own life and she uses it as she thinks the best.

"and she keeps this interest even despite her teachers are ignorant, often she hasn't a challenge."
I'm curious and today what makes her to continue her learnings, to struggle against the circumstances and how to attain such state of mind. Am I loss it somewhere in my childhood when I was afraid to do the opposite the teachers and parents? But in my case it was not the acknowledgement of the importance of learning, it was rather habit. While Lisa's way seems to mean much more wider. Is it really only Marge's contribution? To say honestly I always thought that Lisa's decency is firstly her... female quality rather than personal.

"And then she was disappointed and led to depression  Great expectations bring great disillusionments, and in this world there is always someone who is better than you"
In such case I think it's very useful not to know too much The knowledge is hard especially if you know that at the end the defeat awaits you...
