Nothing so obstinately stands in the way of all sorts of progress as pride of opinion. While nothing is so foolish and baseless.
— Josiah Gilbert Holland

There is great beauty in going through life without anxiety or fear. Half our fears are baseless, and the other half discreditable.
Christian Nevell Bovee baseless quote

Humane sentiments are baseless, mad, and improper; they are incredibly feeble; never do they withstand the gainsaying passions, never do they resist bare necessity.
— Marquis De Sade

Our revels now are ended. These our actors, As I foretold you, were all spirits and Are melted into air, into thin air: And, like the baseless fabric of this vision, The cloud-capp'd towers, the gorgeous palaces, The solemn temples, the great globe itself, Yea, all which it inherit, shall dissolve And, like this insubstantial pageant faded, Leave not a rack behind. We are such stuff As dreams are made on, and our little life Is rounded with a sleep.
— William Shakespeare

Evolution is baseless and quite incredible.
— baseless quotation by John Ambrose Fleming
