It is true that the grasping of truth is not possible without empirical basis. However, the deeper we penetrate and the more extensive and embracing our theories become the less empirical knowledge is needed to determine those theories.
Albert EinsteinThe thinking that got us to where we are is not the thinking that will get us to where we want to be.
Albert EinsteinThe intuitive mind is a sacred gift and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift. We will not solve the problems of the world from the same level of thinking we were at when we created them. More than anything else, this new century demands new thinking: We must change our materially based analyses of the world around us to include broader, more multidimensional perspectives.
Albert EinsteinPhysical concepts are free creations of the human mind, and are not, however it may seem, uniquely determined by the external world.
