" A time comes when silence is betrayal." - As quoted by Martin Luther King, Jr. Whether you are talking about a military conflict or a the battle of ideas, it is generally better to have a large army than a small one. The more individuals we have supporting and defending our core values, the more we are able to defeat the enemies of reason. And yet, countless people that share our values fail to speak up. The reasons for their reluctance are numerous. Most people are too busy to notice the dangers of idea pathogens or wrongly assume that they are unimportant. The intrusion of anti-science, anti-reason, and illiberal movements occurs slowly and incrementally without many people becoming aware of the larger problem. Instead of ignoring the problem, recognize that while it affects others today, it could reach you tomorrow. Most people are reluctant to join the battle of ideas is what is called the "diffusion of responsibility" or "the bystander effect"...
pragmatism | /ˈpraɡməˌtizəm/ : a philosophical approach based on the principle that the usefulness, workability, and practicality of ideas, policies, and proposals are the criteria of their merit. It stresses the priority of action over doctrine, of experience over fixed principles, and it holds that ideas borrow their meanings from their consequences and their truths from their verification.
