Internal

Life is short, art long, opportunity fleeting, experiment fallible, judgment difficult. — Hippocrates

In an evolution-based world-view, "progress" is nothing like the core certainty of an Enlightenment world-view. But looking at life's evolution on Earth, increasing complexity shows up in the distinction between an organism's internal state, and its external environment. Over eons, the inner state evolved from the membranes of early bacteria, to the complex skin and homeostatic mechanisms of modern mammals, to an even richer internal state: the mind, with memory, awareness, and will.

On limist.com, "Internal" topics include either contemplative or mind-body pursuits I enjoy indulging in:

• Body disciplines
• Critical thinking, rhetoric, and meta-cognition
• Learning
• Life — general challenges, strategy, tactics
• Mysticism
• Philosophy
• Poetry
