“The last word in ignorance is the man who says of an animal or plant: 'What good is it?”

Lo que dicen las palabras no dura. Duran las palabres. Porque las palabras son siempre las mismas y lo que dicen no es nunca lo mismo.

As quoted in The Anchor Book of French quotations, with English Translations (1963) by Norbert Guterman

"I Died as a Mineral", as translated in The Mystics of Islam (1914) edited by Reynold Alleyne Nicholson, p. 125
Variant translation: Originally, you were clay. From being mineral, you became vegetable. From vegetable, you became animal, and from animal, man. During these periods man did not know where he was going, but he was being taken on a long journey nonetheless. And you have to go through a hundred different worlds yet.
As quoted in Multimind (1986) by Robert Ornstein
Context: I died as a mineral and became a plant,
I died as plant and rose to animal,
I died as animal and I was Man.
Why should I fear? When was I less by dying?
Yet once more I shall die as Man, to soar
With angels blest; but even from angelhood
I must pass on: all except God doth perish.
When I have sacrificed my angel-soul,
I shall become what no mind e'er conceived.
Oh, let me not exist! for Non-existence
Proclaims in organ tones, To Him we shall return.

Section 3 : Work Democracy versus Politics. The Natural Social Forces for the Mastery of the Emotional Plague;
Variant translation: The cry for freedom is a sign of suppression. It will never cease as long as man feels himself to be trapped. No matter how different the cries for freedom may be, at bottom they always express one and the same thing: the intolerableness of the organism's rigidity and the mechanical institutions of life, which are sharply at variance with the natural sensations of life. ... Not until man acknowledges that he is fundamentally an animal, will he be able to create a genuine culture.
The Mass Psychology of Fascism (1933), Ch. 10 : Work Democracy
Context: The cry for freedom is a sign of suppression. It will not cease to ring as long as man feels himself captive. As diverse as the cries for freedom may be, basically they all express one and the same thing: The intolerability of the rigidity of the organism and of the machine-like institutions which create a sharp conflict with the natural feelings for life. Not until there is a social order in which all cries for freedom subside will man have overcome his biological and social crippling, will he have attained genuine freedom. Not until man is willing to recognize his animal nature — in the good sense of the word — will he create genuine culture.
