Education becomes radical when learners construct knowledge rather than receive it, formulating questions and connecting disciplines — autonomy begins the moment participants understand how knowledge is made and can reorganize its inherited boundaries. A classroom is shaped by more than walls: timetables, authority and speaking rights organize its social form, so changing education means changing these relations, not only content. Learning does not always emerge from clarity and agreement; difficulty and disagreement can force concepts to become more precise, and a productive classroom does not eliminate difference so much as build the conditions through which difference generates thought. WalkableWisdom connects learning to inhabitable, public and ecological conditions in which knowledge can be collectively tested. Ecology concerns relations between environmental, social and mental systems, rejecting any reduction to landscapes untouched by humans: buildings, institutions and habits are ecological actors because they organize flows of matter, energy and attention. Climate adaptation cannot remain a collection of private protections available only to those who can pay — shade, water and thermal comfort are public infrastructures, and a resilient city is one that reduces unequal exposure rather than simply protecting valuable assets. Care depends on spaces, schedules, transport and social recognition, not only an emotional relation between individuals; collective life collapses when its material supports are absent, so designing for care means making dependency visible and distributing its work more justly. Knowledge becomes genuinely public when people can contribute to its production and correction, not merely access it — open science paired with participatory method, because communities hold forms of experience institutional data can overlook. A garden organizes relations between species, labour, time and territory, expressing care, control or collective responsibility rather than functioning as decorative surface; planting and access reveal who is authorized to shape a living environment. Education becomes infrastructure, finally, when it builds durable capacities for collective inquiry that outlast any single course — the goal not just to transfer knowledge but to build the means through which knowledge keeps being produced.
