Immanuel Kant argued for objective morality based on synthetic apriori. He cited mathematics as an example of synthetic apriori. He said we understand the observable universe through maths, maths comes about through logical statements, therefore it's possible to know objective reality, including things impossible to observe, strictly through intellect. If maths is an objective reality we understand through deduction, then it is possible to deduce objective morality through the same process.

His mistake was that maths is a tool used by science to model observations. If the observation is incomplete, the model is incomplete. It's impossible to observe everything because we are limited by time and space in our ability to observe.

Furthermore, Kant heavily cited Euclidean geometry as an objective reality. He had limited knowledge of maths, so he didn't know about Topology, a non-Euclidean geometry whose very existence refutes the supposed universality of Euclidean geometry. For example, it's possible on a hyperbolic surface to have a triangle with internal angles less than 180 degrees, something that goes against the Euclidean triangle angle sum theorem that the internal angles of a triangle always equal 180 degrees.

TLDR; No, I don't believe in objective morality.
