Heaven knows what seeming nonsense may not to-morrow be demonstrated truth. - Alfred North Whitehead

Presentational immediacy is our immediate perception of the contemporary external world, appearing as an element constitutive of our own experience. In this appearance the world discloses itself to be a community of actual things, which are actual in the same sense as we are.

In a sense, all explanation must end in an ultimate arbitrariness.

You cannot think without abstractions; accordingly, it is of the utmost importance to be vigilant in critically revising your modes of abstraction. It is here that philosophy finds its niche as essential to the healthy progress of society. It is the critic of abstractions. A civilisation which cannot burst through its current abstractions is doomed to sterility.
