Yes, I recognize the above post is written from a left-wing perspective. I'm not invested in the claims so much as in the idea that some sort of considered project is necessary if we'll be coming up with new ideologies suited for a globalized world. (I'll borrow a definition of "ideology" from Wikipedia for illustration's sake.)
An ideology is a set of ideas that directs one's goals, expectations, and actions. An ideology can be thought of as a comprehensive vision, as a way of looking at things (compare worldview), as in common sense (see Ideology in everyday society below) and several philosophical tendencies (see Political ideologies), or a set of ideas proposed by the dominant class of a society to all members of this society (a 'received consciousness' or product of socialization). The main purpose behind an ideology is to offer change in society, and adherence to a set of ideals where conformity already exists, through a normative thought process. Ideologies are systems of abstract thought (as opposed to mere ideation) applied to public matters and thus make this concept central to politics. Implicitly every political tendency entails an ideology whether or not it is propounded as an explicit system of thought.
Mind, do we actually need new ones?
This post is more of a [FORUM] post than most. I've no particular interest in formulating any new ideology, religious or secular, left or right, whatever--it's just not relevant to me personally, or politically, at this point in my life. I've no time or energy for it. Call me a devotee of "well-meaning detail-orientedness," if you must. Others reading this, I know, do find this relevant and do have the interest in it. What say you all?
