知识论

知 = 口 + 矢 : Mnemonic symbol: Francis Bacon is attributed to have stated "scientia potentia est", "knowledge is power". I'll thus represent 知 by Francis Bacon. Francis Bacon (知) and James II of England (zh) are playing darts (矢) in front of the space station (Ø1). Because they lack a dart board they just use a mandarin (口).

识 = 只 + 讠 : Sherlock Holmes (sh) is inspecting the new arrival at the entrance of the space station (Ø2). It's a big advertising column (讠) with a cuttlefish (只) on it, to broaden the space station's inhabitant's knowledge (识).

论 = 仑 + 讠 : Lenny Lemur (lu) finds an advertising column (讠) in the encampment's bathroom ((e)n4) and on it a discussion (论) of his blackcurrant wine (仑). The discussion (论) is very negative and so Lenny angrily throws blackcurrants at it, messing up the ad.
