I don't think faith in the future is enough.

I agree with you. It is not enough for me, either.

I lack the time (and possibly the talent) to be a Renaissance Man. I try to learn a little bit about everything. What I don't know I have to take on faith.

it's foolish not to do the best we can with what we've currently got to limit the scope of crises such as the climate crisis, to give the future the best possible fighting chance.

Again, we agree.

However. Take care that your actions today do not unduly hinder our possibilities for tomorrow.
