Which do we need more!

Science explain How things happen and Philosophy explains why things happen!

Science has lowered the bar on factual-proof, and allowed so much politics, and agendas in the actual science, that you could say: Science = Philosophy now.

So the dynamic is your answer, we need Pilosophy more. Or we would be more vigilant in protecting hard-/factual-science.

In essence, your question poses an answer in itself. Science may explain every single process in the universe, but science will never be able to determine human nature no matter how much we learn about neurobiology/psychology. I might also add that although science does explain many processes through factual information, those processes can still be subject to change. No matter how many scientific answers we have, we will never understand it all because the more we understand, the more questions we have. For instance, long ago "scientists" thought the solar system revolved around the Earth not the sun. Obviously we know that's not true. But when they believed it, they claimed it as "fact". No one can truly fathom the depth of the human psyche. For that reason, you could even argue that philosophy is science and vice versa. There will always be unanswerable questions. You must ask yourself this, "do I care more about the outcome or the process?".

Chicken n egg stuff.

Any kind of reasoned thought must require an action/ task and a conslusion/ result.

Without them blending together, all action would be pointless.

Which do we need more? Yes, we do.
