Culture and education have no bounds or limits; now man is in a phase in which he must decide for himself how far he can proceed in the culture that belongs to the whole of humanity.
Maria MontessoriLet the children be free; encourage them; let them run outside when it is raining; let them remove their shoes when they find a puddle of water; and when the grass of the meadows is wet with dew, let them run on it and trample it with their bare feet; let them rest peacefully when a tree invites them to sleep beneath its shade; let them shout and laugh when the sun wakes them in the morning.
Maria MontessoriPraise, help, or even a look, may be enough to interrupt him, or destroy the activity. It seems a strange thing to say, but this can happen even if the child merely becomes aware of being watched. After all, we too sometimes feel unable to go on working if someone comes to see what we are doing. The great principle which brings success to the teacher is this: as soon as concentration has begun, act as if the child does not exist. Naturally, one can see what he is doing with a quick glance, but without his being aware of it.
