The claim is also sometimes made that science is as arbitrary or irrational as all other claims to knowledge, or that reason itself is an illusion. As Ethan Allen said Those who invalidate reason ought seriously to consider whether they argue against reason with or without reason; if with reason, then they establish the principle that they are labouring to dethrone. If they argue without reason, which they must do, in order to be consistent with themselves, they are out of reach of rational conviction, nor do they deserve a rational argument.
Carl SaganThere are many hypotheses in science which are wrong. Thatโs perfectly all right: itโs the aperture to finding out whatโs right. Science is a self-correcting process.
Carl SaganWe have entered, almost without noticing, an age of exploration and discovery unparalleled since the Renaissance.
