"Repetimos que o conhecimento não se estende do que se julga sabedor até aqueles que se julga não saberem; o conhecimento se constitui nas relações homem-mundo; relações de transformação, e se aperfeiçoa na problematização crítica destas relações.“ Paolo Freire

We have lingered in the chambers of the seaBy sea-girls wreathed with seaweed red and brown
Till human voices wake us, and we drown.

SUMMARY• Evidence based medicine is about patients, not
about evidence• The epistemological crisis in medicine and
healthcare must be addressed if the practical challenges are to be solved
• Scientifically informed, effective care,requires “critical problematization” across all parties
• This means “education for critical consciousness”
