That we should not rely on science alone to discern meaning in our lives.
Science doesn't discern anything, Alan: it just provides various forms of information that allows people to do the discerning. Not everyone discerns things equally well though since issues like relevant experience, the existing knowledge or degree of ignorance a person has about the subject matter, how capable they are at scrutinising relevant information, that they accept that scientific knowledge is provisional and may be incomplete and, of course, any biases they have. All these aspects play a part in the discerning process.
Your 'not relying on science alone' approach implies you think there are other methods that you don't ever specify in terms equivalent to the robustness of science, which leaves the door open for the gullible to be influenced by all sorts of psuedoscientific woo, magical thinking, superstitions and poor reasoning - and we regularly see examples of these in this wee forum.
