"To unfold the secret laws and relations of those high faculties of thought by which all beyond the merely perceptive knowledge of the world and of ourselves is attained or matured, is a object which does not stand in need of commendation to a rational mind"
About this Quote
The phrasing matters. “High faculties of thought” elevates cognition into a kind of intellectual aristocracy, distinguishing it from “merely perceptive knowledge” - the raw data of sensation. That contrast is the subtext: observation alone is not wisdom. What matures knowledge is structure: the internal machinery that turns facts into understanding, self-knowledge into something sturdier than introspection.
Then comes the rhetorical flex: this aim “does not stand in need of commendation to a rational mind.” Translation: if you need persuading, you’re not the audience. It’s a gatekeeping move, but also a strategic one. Boole is positioning his work not as a quirky philosophical side quest but as the natural agenda of any “rational” person - a subtle bid to legitimate abstract inquiry at a time when utility-minded readers might ask what any of this is for.
Contextually, it’s a mission statement for what becomes modern logic and, eventually, computation: treat thinking as something with discoverable laws, and you can engineer clarity where intuition has been running the show.
