“The true dualism I take to be the contrast between two wills, one of which is felt as vital impulse (élan vital) and the other as vital control”

Context: Creativity is the result of a struggle between vitality and form. As anyone who has tried to write a sonnet or scan poetry, is aware, the form ideally do not take away from the creativity but may add to it.

The Relation of the State to the Invididual (1890)
Context: This distinction between invasion and resistance, between government and defence, is vital. Without it there can be no valid philosophy of politics. Upon this distinction and the other considerations just outlined, the Anarchists frame the desired definitions. This, then, is the Anarchistic definition of government: the subjection of the non-invasive individual to an external will. And this is the Anarchistic definition of the State: the embodiment of the principle of invasion in an individual, or a band of individuals, assuming to act as representatives or masters of the entire people within a given area.

Transition (1927)
Context: I felt more keenly than before the need of a philosophy that would do justice to the infinite vitality of nature. In the inexhaustible activity of the atom, in the endless resourcefulness of plants, in the teeming fertility of animals, in the hunger and movement of infants, in the laughter and play of children, in the love and devotion of youth, in the restless ambition of fathers and the lifelong sacrifice of mothers, in the undiscourageable researches of scientists and the sufferings of genius, in the crucifixion of prophets and the martyrdom of saints — in all things I saw the passion of life for growth and greatness, the drama of everlasting creation. I came to think of myself, not as a dance and chaos of molecules, but as a brief and minute portion of that majestic process... I became almost reconciled to mortality, knowing that my spirit would survive me enshrined in a fairer mold... and that my little worth would somehow be preserved in the heritage of men. In a measure the Great Sadness was lifted from me, and, where I had seen omnipresent death, I saw now everywhere the pageant and triumph of life.
