A 1031 No.

There is no density specification for settlements in D&D; this is left to each individual DM to decide during world building.

A Wizard may know any number of spells, but the number known is a limited subset of their class list. Spells known refers to those spells the Wizard has learned either automatically from class abilities (initial level 0 and 1 spells, plus 2 spells per subsequent level) or as demonstrated by the relevant successful Spellcraft checks and study days. See the primary definition of learn: "to acquire knowledge of or skill in by study, instruction, or experience". It is not necessary for the Wizard to have written these spells in a spellbook, but they must have succeeded on all tasks leading up to the actual writing.

The class description says the Soulknife gains the feat automatically (regardless of prerequisites), but does not except the character from the usual feat requirements for use. Speed of Thought, like most feats, cannot be used if the character does not meet the prerequisites.
