What parts of Muslim philosophy and learning do we see in our own culture today?

If we look at the five principles of Islam, or the five pillars or the five fundamentals, belief practically ends with the first pillar of Islam. In other words, that affirmation that Allah is the only deity and that Muhammad is his messenger. After that, everything is action, is practice. The other four, i. e., praying, fasting, paying the zakat - - what I call a social tax - - and the hajj, involve action. Muslims are very action-oriented.
