Famous quotes containing the words medical and/or conditions:
“Every day our garments become more assimilated to ourselves, receiving the impress of the wearer’s character, until we hesitate to lay them aside without such delay and medical appliances and some such solemnity even as our bodies.”
—Henry David Thoreau (1817–1862)
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
