Now all the knowledge and wisdom that is in creatures, whether angels or men, is nothing else but a participation of that one eternal, immutable and increased wisdom of God.

The stars look the same from night to night. Nebulae and galaxies are dully immutable, maintaining the same overall appearance for thousands or millions of years. Indeed, only the sun, moon and planets - together with the occasional comet, asteroid or meteor - seem dynamic.

We say that a human being is a person and a distinctive, fixed self with a name and a life. He has an identity. But what is this self really made of, except from the basic elements such as hydrogen, carbon, oxygen, phosphorus etc. and their subatomic particles? If a person is a specific, static, unchanged entity and existence, then what if an accident or a disease completely alters his body features? What if fear or madness changes his thoughts and perceptions? If dementia takes away his memories, or if drugs alter his emotions? And what if life circumstances, good or bad luck, modify his motives, his plans and his desires? Is it still the person we say he is? Or is selfhood a ghost, a useful fiction of the brain? An ever-shifting kaleidoscope of thoughts, feelings and perceptions? Flashes of hopes and desires? A bundle of alternating opinions and ideologies, of conflicting instincts and urges? If we take away all these from him, what would be left behind? If every drop of the ocean evaporates, is not the whole ocean gone? The immutable selfhood is a very old illusion and the last of illusions we 're going to abandon; if we ever will?

A philosopher is a lover of wisdom, not of knowledge, which for all its great uses ultimately suffers from the crippling effect of ephemerality. All knowledge is transient linked to the world around it and subject to change as the world changes, whereas wisdom, true wisdom is eternal immutable. To be philosophical one must love wisdom for its own sake, accept its permanent validity and yet its perpetual irrelevance. It is the fate of the wise to understand the process of history and yet never to shape it.

...reality is always plural and mutable.
