So she is part of the Catalan political class. A few years ago, she explained what she as a modern day leftist believes in:
The true values of today's left are based on ... the authenticity, the acknowledgement of desire as the organizing principle of our life, the coherence of desire with action ..., that is, to live without principles that are external, imposed, limiting, alien to our own needs or to our own personal truth ... The moral of the left involves to take risks, to dare, to follow the personal impulses and, therefore, this line of thinking implies to develop scientific thinking that allows us to control a bit more our life conditions.
I'm not sure which is more striking: the liberalism or the nihilism.
The liberalism comes out in the insistence on autonomy as the sole organising principle of life. What matters to Marina Subirats is that it is our own will, our own authentic desire, which shapes who we are and what we do, without impediment. Those forces which are unchosen, which are external to us, are therefore treated negatively as a restriction or limitation.
But this means that it all becomes subjective. If there can't be an unchosen external source of value, then the only value that an action has is a subjective, personal one - that I happen to desire it. If I cease to desire it, it no longer has any value. There's nothing intrinsic to it of any value.
What is left to Marina Subirats? She has rejected the idea of an objective truth in favour of a merely personal one. And she is reduced to talking about "personal impulse" as a breakthrough good.
