“A seeker after Truth cannot afford to indulge in generalisation. Darwin for the greater part of his book Origin of the Species has simply massed fact upon fact without any theorising, and only towards the end has formulated his conclusion which, because of the sheer weight of testimony behind it, becomes almost irresistible. Yes I have criticised even Darwin's generalisation as being unwarranted. Science tells us that a proposition may hold good in nine hundred ninety-nine cases and yet fail in the thousandth case and thus be rendered untenable as a universal statement.”
