A scheme such as mine is gravely imperiled if it is opposed by "practical" people. Now "practical" people are as a rule nothing more than men sunk into the groove of daily routine, unable to emerge from a narrow circle of antiquated ideas. At the same time, their adverse opinion carries great weight, and can do considerable harm to a new project, at any rate until this new thing is sufficiently strong to throw the "practical" people and their mouldy notions to the winds.
