Such a deeper expansion of social welfare—seeing to that all citizens (or as many as practically possible) grow up genuinely healthy and emotionally well-developed—is both possible and necessary.
This core philosophy of meta-modernism is Tillich's answer to the ailments of society of his time and a response to capitalism and its discontents.
The protestant principle is a secular idea. Or trans-secular. It involves the struggle or the valiant attempt to retain this perspective at all times...once the core of its function is forgotten, objective realities are set into their places. Ones great ideas are anothers nightmares...anyone can be a part of this principle (beyond class, any divisions of human-ness).
The Protestant principle provides the possibility for understanding the paradoxical character of anticipation as it is found in the proletariat, and, besides this, it has the power to guard against a distortion that threatens all anticipation, i.e., utopianism. The attitude of anticipation develops into utopianism if it is allowed to lose its essential dialectical character and is held as g a precise and literal intellectual anticipation—an anticipation that at some time in the future is to be replaced by a tangible, objective possession. The thinultimately referred to in all genuine anticipation remains transcendent; it transcends any concrete fulfillment of human destiny; it transcends the otherworldly utopias of religious fantasy as well as the this-worldly utopias of secular speculation. And yet this transcendence does not mean that distorted reality should be left unchanged; rather it looks forward to a continuous revolutionary shattering and transforming of the existing situation. Thus proletarian anticipation involves a real change in proletarian existence, a real shattering and overcoming of capitalism. But it does not and cannot involve the bringing-about of a situation that is exempt from the threat that always confronts human existence.
