We, the “revolutionaries”, the “overthrowers” — we are thriving far better on legal methods than on illegal methods and overthrow. The parties of order, as they call themselves, are perishing under the legal conditions created by themselves. They cry despairingly with Odilon Barrot: la légalité nous tue, legality is the death of us; whereas we, under this legality, get firm muscles and rosy cheeks and look like life eternal. And if we are not so crazy as to let ourselves be driven to street fighting in order to please them, then in the end there is nothing left for them to do but themselves break through this dire legality.
