The scientific spirit is of more value than its products, and irrationally held truths may be more harmful than reasoned errors.
Thomas Henry Huxley.
Accidental truth of a conclusion is no compensation for erroneous deduction.
The very truth, and the nature of things, though repudiated and ordered into exile, sneaked in again through the back door, to be received by me under an unwonted guise.
