Travelers and philosophers are pushing the limits of their knowledge, seeing how the world works. There is an undeniable link in exploring the oceans and even other planets, and in crafting radically new questions delving into the mind's uncharted territory.

The tools may be different, but the essential journey is the same, with travelers affecting philosophy and philosophers affecting travel.

For Zen practitioners, life is transitory and insubstantial. There is no security and thinking otherwise is a waste of time. 

They also don’t believe in an afterlife. Reincarnation can be more accurately thought of as a constant rebirth, of death throughout life, and the continual coming and going of universal energy before and after death.

The word 'Zen' means emptiness or void. This is the basis of Zen — that all that exists is based on a dynamic emptiness. Which is also what quantum science says.

In this view, there is no difference between matter and energy. Look at anything closely enough and you will see that it is an event, not a thing. Furthermore, there is not a ‘multiplicity of events’. There is just one event, with multiple aspects, unfolding. 

"Science is what you know. Philosophy is what you don’t know."

Philosophy is examining our understanding of reality and knowledge. Philosophy consists of three major branches:

1. Metaphysics - What is true about existence.
2. Epistemology - How we can know that it is true. Epistemology has given us science, logic/reason, economics, psychology, and other theories of knowledge.
3. Ethics - What actions we should take as a result of this knowledge. Ethics contains concepts such as democracy, human rights, the treatment of animals, and the environment.

When you order your thoughts into a coherent belief system, you are engaging in philosophy. To criticize philosophy, you must rely on philosophy.
