 At the end of the day one should not lose sight of the larger context that sustains problems and projects in most disciplines and practices. We are as free to pursue them as Kant’s dove is free to fly, that is, not without the surrounding air resistance to flap its wings upon and against. Philosophy was once thought to stand for the systematic unity of the sciences. The foundational character of unity became the distinctive project of philosophy, in which conceptual unity played the role of the standard of intelligibility. In addition, the ideal of unity, frequently under the guise of harmony, has long been a standard of aesthetic virtue (This image has been eloquently challenged by, for instance, John Bailey and Iris Murdoch; Bailey 1976; Murdoch 1992).  Unities and unifications help us meet cognitive and practical demands upon our life as well as cultural demands upon our self-images that are both cosmic and earthly. It is not surprising that talk of the many meanings of unity, namely, fundamental level, unification, system, organization, universality, simplicity, atomism, reduction, harmony, complexity or totality, can bring an urgent grip on our intellectual imagination.
