Do I really need to explain that science is not separate from philosophy?
Science intersects with philosophy, though in our modern world this intersection is getting smaller.
Philosophy in ancient Greece had the weight of science today.
Natural philosophy dealt with subjects only the mind could contemplate, but some of the concepts are still valid today, like the fact that everything is built with the same matter: man and rock for example. The ancient Greeks had no way to look into atoms but they knew this. With the evolution of science we were able to prove this.
Modern natural philosophy consists of theories that are spun from the results that science has brought up so far. Theories are useful, because they set a path for research to follow.
You could be skeptic about matter being made up of atoms, because you can't see atoms.
This society believes the Earth is flat and we live in a geocentric system. Its bright members refute claims that are only verifiable by a handful of people.
That the earth is round can only be proven with indirect methods involving observation, physics and mathematics. The problem is that if the indirect proof is rock solid, FE believers will drift away from the subject core and start babbling until the thread dies, and they call themselves undefeated.
But at least I will be satisfied
