The ideas we profess are our beliefs. The ideas we use to produce our thoughts and to guide our actions — these are faith.
The two rarely coincide.
The better a thing is suited to its purpose, and the more skillful we become using it, the less we notice that thing while we are using it.
For instance, when we write, we are are absorbed in the words we are saying more than we are thinking about grammar, or the letters that make up the words, or the shapes of the letters, or the movement of our hands, or how we are manipulating the pen. Only when we hit a difficulty using one of these layers of tools do we stop and notice and think about what we are doing.
The concepts we use are the same way. They are extensions of our mind to the point where they seem to be mind itself, and we notice only the ideas we make with them. Because of this, we can forget that we can acquire or retire concepts if the thoughts we are making with them, or the actions we perform using them are faulty and lead us into mistakes or confusions.
To philosophize is to intentionally design the conceptual interface between one’s mind and the realities one experiences.
