writing about the legacy of Voltaire a french phlosopher who believed in freedom of religion and right to a fair trial. What do we have today that still uses his works (other than the books he wrote)

Virtually every thought of today refers to an ancient Greek philosopher, be it in Politics or Aesthetics. Are there any Greek philosophers that are impertinent in today’s world ?

Religion without the Holy Spirit Christianity without Christ Forgiveness without regeneration Salvation without regeneration Politics without God Heaven without Hell The Renaisance eliminated sin – French philosophers said we are all good Classical era eliminated revelation – we have to be rational Modern era eliminated faith – Just believe in science what you can see. Post Modern era eliminated God – there is no god, materialism Post Christian era – eliminated Christianity – we tried Christ, but found Christianity lacking.
