40d:Thought

Dwarf psychology is not all that complex - various events cause dwarves to gain 'thoughts'. Thoughts have a happiness/unhappiness value. The value of all the thoughts a particular dwarf has is simply summed to determine how happy or unhappy they are. If dwarves are particularly unhappy, they may throw tantrums, and may enter fell or macabre strange moods.

To view a dwarf's thoughts, press v on the dwarf. Then press p(preferences) -> z -> enter.
Now you will see descriptions on how the dwarf feels (Ecstatic, happy, content, unhappy, miserable), and what recent events made an impact on the dwarf. There are also some personal traits listed on the bottom.
