Not exactly. I don't know how others do this, but border cities need as much culture as they can get. When I take over another civ's city, they tend to be at a huge cultural disadvantage when bordering other civs' cities which are already highly developed. I need these cultural building as a buffer against them.
I handle border issues very simply...I kill them or vassal them. Fighting for culture is "passive" play..just saying.
Really? In that case, maybe the reason I can't is that I've discovered Scientific Method
So, once I've discovered SM, then all the monasteries I've built are all I'm every going to have? And if I'm not working the Organized Religion civic, I'm not going to be able to build any missionaries in cities that don't already have the monasteries, so I won't be able to propagate religion? That puts me in a difficult situation, because the way I play, I tend to be a bit late to do the missionary work. If I want to propagate a religion at this stage (which would be purely for cultural reasons) is there a better way than switching to OR?
SM disables the monastery bonuses (science and mishes) and ability to build new ones - existing monasteries and their culture bonus remain though. OR would be your only way to spread religion yourself. If religion is important to your game, and religious civics like OR are powerful, then you should spread the adopted religion as soon as you can. AIs will often spread much of their religion. OR and Pacifism are really THE religious civics to run anyway, but usually I just stay in OR much of the game unless I opt for Free Religion later. (Note: In BTS, Golden Ages boost great person production 100% like Pacifism and this is usually when I run Pacifism to really pump out great folks fast)
Also, note that in BTS the Apostolic Palace feature is added, when gives +2
for AP religious buildings. So I tend to spread the AP religion whether I adopt that or not, also to be more of a factor in AP voting. (there is a new AP diplo victory as well or essentially a religious diplo victory)
BTS is THE definitive version of Civ IV, and I highly recommend you acquire a copy asap. IV Complete version often goes on sale on sites like Steam or GOG.com for around 7 bucks. Lot's of improvements over the prior versions including many addtions, but also better culture mechanics earlier (monuments expire at Astro, not Calendar), and war weariness has been toned down considerably as it was pretty ridiculous in vanilla.
BUG + BULL mod significantly improves the UI and info screens. (Note: If you can to play vanilla Civ for now, I recommend installing the HOF mod for vanilla. You can go into the option screens and select some of the checkboxes to add improved advisor screens, which are just plain terrible in vanilla). You can find it here - just select the link at the top "Civ IV Download":

Regardless, BTS is the way to go. Plus, once you get it you can participate in many things over in the Strategy & Tips forum to really learn how to play the game, as well enjoy Game of the Months and HOF games (see my sig). Lots of fun to be had with this game, and lots to learn.
